用处及效果
准备工作
思路如下:
1、确定哪些控件需要进行验证,在组件中进行属性扩展
2、定义验证规则
3、根据验证规则的正则表达式进行验证和非空验证
4、触发验证结果事件
5、进行验证结果提示
开始
添加一个验证规则枚举
1 /// <summary> 2 /// 验证规则 3 /// </summary> 4 public enum verificationmodel 5 { 6 /// <summary> 7 /// 无 8 /// </summary> 9 [description("无"), verificationattribute()] 10 none = 1, 11 /// <summary> 12 /// 任意字母数字下划线 13 /// </summary> 14 [description("任意字母数字下划线"), verificationattribute(@"^[a-za-z_0-1]*$", "请输入任意字母数字下划线")] 15 anychar = 2, 16 /// <summary> 17 /// 任意数字 18 /// </summary> 19 [description("任意数字"), verificationattribute(@"^[\-\+]?\d+(\.\d+)?$", "请输入任意数字")] 20 number = 4, 21 /// <summary> 22 /// 非负数 23 /// </summary> 24 [description("非负数"), verificationattribute(@"^(\+)?\d+(\.\d+)?$", "请输入非负数")] 25 unsignnumber = 8, 26 /// <summary> 27 /// 正数 28 /// </summary> 29 [description("正数"), verificationattribute(@"(\+)?([1-9][0-9]*(\.\d{1,2})?)|(0\.\d{1,2})", "请输入正数")] 30 positivenumber = 16, 31 /// <summary> 32 /// 整数 33 /// </summary> 34 [description("整数"), verificationattribute(@"^[\+\-]?\d+$", "请输入整数")] 35 integer = 32, 36 /// <summary> 37 /// 非负整数 38 /// </summary> 39 [description("非负整数"), verificationattribute(@"^(\+)?\d+$", "请输入非负整数")] 40 unsignintegernumber = 64, 41 /// <summary> 42 /// 正整数 43 /// </summary> 44 [description("正整数"), verificationattribute(@"^[0-9]*[1-9][0-9]*$", "请输入正整数")] 45 positiveintegernumber = 128, 46 /// <summary> 47 /// 邮箱 48 /// </summary> 49 [description("邮箱"), verificationattribute(@"^(([0-9a-za-z]+)|([0-9a-za-z]+[_.0-9a-za-z-]*[0-9a-za-z]+))@([a-za-z0-9-]+[.])+([a-za-z]{2}|net|net|com|com|gov|gov|mil|mil|org|org|edu|edu|int|int)$", "请输入正确的邮箱地址")] 50 email = 256, 51 /// <summary> 52 /// 手机 53 /// </summary> 54 [description("手机"), verificationattribute(@"^(\+?86)?1\d{10}$", "请输入正确的手机号")] 55 phone = 512, 56 /// <summary> 57 /// ip 58 /// </summary> 59 [description("ip"), verificationattribute(@"(?=(\b|\d))(((\d{1,2})|(1\d{1,2})|(2[0-4]\d)|(25[0-5]))\.){3}((\d{1,2})|(1\d{1,2})|(2[0-4]\d)|(25[0-5]))(?=(\b|\d))", "请输入正确的ip地址")] 60 ip = 1024, 61 /// <summary> 62 /// url 63 /// </summary> 64 [description("url"), verificationattribute(@"^[a-za-z]+://(//w+(-//w+)*)(//.(//w+(-//w+)*))*(//?//s*)?$", "请输入正确的网址")] 65 url = 2048, 66 /// <summary> 67 /// 身份证号 68 /// </summary> 69 [description("身份证号"), verificationattribute(@"^[1-9]\d{5}(18|19|([23]\d))\d{2}((0[1-9])|(10|11|12))(([0-2][1-9])|10|20|30|31)\d{3}[0-9xx]$", "请输入正确的身份证号")] 70 idcardno = 4096, 71 /// <summary> 72 /// 正则验证 73 /// </summary> 74 [description("自定义正则表达式"), verificationattribute()] 75 custom = 8192, 76 }
还有一个验证规则枚举的特性
1 public class verificationattribute : attribute 2 { 3 /// <summary> 4 /// initializes a new instance of the <see cref="verificationattribute"/> class. 5 /// </summary> 6 /// <param name="strregex">the string regex.</param> 7 /// <param name="strerrormsg">the string error msg.</param> 8 public verificationattribute(string strregex = "", string strerrormsg = "") 9 { 10 regex = strregex; 11 errormsg = strerrormsg; 12 } 13 /// <summary> 14 /// gets or sets the regex. 15 /// </summary> 16 /// <value>the regex.</value> 17 public string regex { get; set; } 18 /// <summary> 19 /// gets or sets the error msg. 20 /// </summary> 21 /// <value>the error msg.</value> 22 public string errormsg { get; set; } 23 24 }
定义事件参数
1 public class verificationeventargs : eventargs 2 { 3 /// <summary> 4 /// gets or sets the verification control. 5 /// </summary> 6 /// <value>the verification control.</value> 7 public control verificationcontrol { get; set; } 8 /// <summary> 9 /// gets or sets a value indicating whether [verify success]. 10 /// </summary> 11 /// <value><c>true</c> if [verify success]; otherwise, <c>false</c>.</value> 12 public bool isverifysuccess { get; set; } 13 /// <summary> 14 /// gets or sets the verification model. 15 /// </summary> 16 /// <value>the verification model.</value> 17 public verificationmodel verificationmodel { get; set; } 18 /// <summary> 19 /// 是否已处理,如果为true,则不再使用默认验证提示功能 20 /// </summary> 21 /// <value><c>true</c> if this instance is processed; otherwise, <c>false</c>.</value> 22 public bool isprocessed { get; set; } 23 /// <summary> 24 /// gets or sets 正则表达式 25 /// </summary> 26 /// <value>the custom regex.</value> 27 public string regex { get; set; } 28 /// <summary> 29 /// gets or sets a value indicating whether this <see cref="verificationeventargs"/> is required. 30 /// </summary> 31 /// <value><c>true</c> if required; otherwise, <c>false</c>.</value> 32 public bool required { get; set; } 33 34 /// <summary> 35 /// gets or sets the error msg. 36 /// </summary> 37 /// <value>the error msg.</value> 38 public string errormsg { get; set; } 39 }
添加一个类verificationcomponent继承component,实现接口 iextenderprovider以对控件进行扩展
定义属性
1 /// <summary> 2 /// delegate verificationedhandle 3 /// </summary> 4 /// <param name="e">the <see cref="verificationeventargs"/> instance containing the event data.</param> 5 public delegate void verificationedhandle(verificationeventargs e); 6 /// <summary> 7 /// occurs when [verificationed]. 8 /// </summary> 9 [browsable(true), category("自定义属性"), description("验证事件"), localizable(true)] 10 public event verificationedhandle verificationed; 11 12 /// <summary> 13 /// the m control cache 14 /// </summary> 15 dictionary<control, verificationmodel> m_controlcache = new dictionary<control, verificationmodel>(); 16 /// <summary> 17 /// the m control regex cache 18 /// </summary> 19 dictionary<control, string> m_controlregexcache = new dictionary<control, string>(); 20 /// <summary> 21 /// the m control required cache 22 /// </summary> 23 dictionary<control, bool> m_controlrequiredcache = new dictionary<control, bool>(); 24 /// <summary> 25 /// the m control msg cache 26 /// </summary> 27 dictionary<control, string> m_controlmsgcache = new dictionary<control, string>(); 28 /// <summary> 29 /// the m control tips 30 /// </summary> 31 dictionary<control, forms.frmanchortips> m_controltips = new dictionary<control, forms.frmanchortips>(); 32 33 /// <summary> 34 /// the error tips back color 35 /// </summary> 36 private color errortipsbackcolor = color.fromargb(255, 77, 58); 37 38 /// <summary> 39 /// gets or sets the color of the error tips back. 40 /// </summary> 41 /// <value>the color of the error tips back.</value> 42 [browsable(true), category("自定义属性"), description("错误提示背景色"), localizable(true)] 43 public color errortipsbackcolor 44 { 45 get { return errortipsbackcolor; } 46 set { errortipsbackcolor = value; } 47 } 48 49 /// <summary> 50 /// the error tips fore color 51 /// </summary> 52 private color errortipsforecolor = color.white; 53 54 /// <summary> 55 /// gets or sets the color of the error tips fore. 56 /// </summary> 57 /// <value>the color of the error tips fore.</value> 58 [browsable(true), category("自定义属性"), description("错误提示文字颜色"), localizable(true)] 59 public color errortipsforecolor 60 { 61 get { return errortipsforecolor; } 62 set { errortipsforecolor = value; } 63 }
哪些控件需要进行验证(属性扩展)
1 public bool canextend(object extendee) 2 { 3 if (extendee is textboxbase || extendee is uctextboxex || extendee is combobox || extendee is uccombox) 4 { 5 return true; 6 } 7 return false; 8 }
