C#实现读写ini文件类实例

本文实例讲述了c#实现读写ini文件类。分享给大家供大家参考。具体如下：

这个c#类封装了对ini配置文件进行操作所需的各种函数，包括读取键值、读取键值、删除段落等

using system;
using system.runtime.interopservices;
using system.text;
namespace dotnet.utilities
{
  /// <summary>
  /// ini文件读写类。
  /// </summary>
  public class inifile
  {
    public string path;
    public inifile(string inipath)
    {
      path = inipath;
    }
    [dllimport("kernel32")]
    private static extern long writeprivateprofilestring(string section,string key,string val,string filepath);
    [dllimport("kernel32")]
    private static extern int getprivateprofilestring(string section,string key,string def, stringbuilder retval,int size,string filepath);
    [dllimport("kernel32")]
    private static extern int getprivateprofilestring(string section, string key, string defval, byte[] retval, int size, string filepath);
    /// <summary>
    /// 写ini文件
    /// </summary>
    /// <param name="section"></param>
    /// <param name="key"></param>
    /// <param name="value"></param>
    public void iniwritevalue(string section,string key,string value)
    {
      writeprivateprofilestring(section,key,value,this.path);
    }
    /// <summary>
    /// 读取ini文件
    /// </summary>
    /// <param name="section"></param>
    /// <param name="key"></param>
    /// <returns></returns>
    public string inireadvalue(string section,string key)
    {
      stringbuilder temp = new stringbuilder(255);
      int i = getprivateprofilestring(section,key,"",temp, 255, this.path);
      return temp.tostring();
    }
    public byte[] inireadvalues(string section, string key)
    {
      byte[] temp = new byte[255];
      int i = getprivateprofilestring(section, key, "", temp, 255, this.path);
      return temp;
    }
    /// <summary>
    /// 删除ini文件下所有段落
    /// </summary>
    public void clearallsection()
    {
      iniwritevalue(null,null,null);
    }
    /// <summary>
    /// 删除ini文件下personal段落下的所有键
    /// </summary>
    /// <param name="section"></param>
    public void clearsection(string section)
    {
      iniwritevalue(section,null,null);
    }
  }
}

希望本文所述对大家的c#程序设计有所帮助。
