C#简单的向量用法实例教程

本文以实例讲述了c#简单的向量用法，主要包括重载运算符>：以向量长度判断是否为真、重载运算符!=、<、<=等，具体实现代码如下：

using system;
class vector
{
 private double xvector;
 private double yvector;
 //构造函数
 public vector(double x, double y )
 {
 xvector = x;
 yvector = y;
 }
 //获取向量的长度
 public double getlength( )
 {
 double length = math.sqrt( xvector*xvector + yvector*yvector );
 return length;
 }
 //重载运算符==
 public static bool operator == ( vector a, vector b )
 {
 return ( (a.xvector == b.xvector) && (a.yvector == b.yvector) );
 }
 //重载运算符!=
 public static bool operator != ( vector a, vector b )
 {
 return !( a == b );
 }
 //重载运算符>：以向量长度判断是否为真
 public static bool operator > ( vector a, vector b )
 {
 return a.getlength( ) > b.getlength( );
 }
 //重载运算符<
 public static bool operator < ( vector a, vector b )
 {
 return a.getlength( ) < b.getlength( );
 }
 //重载运算符>=
 public static bool operator >= ( vector a, vector b )
 {
 return ( a == b ) || ( a > b );
 }
 //重载运算符<=
 public static bool operator <= ( vector a, vector b )
 {
 return ( a == b ) || ( a < b );
 }
}
class test
{
 static public void main( )
 {
 vector vector1 = new vector( 3, 4 );
 vector vector2 = new vector( 0, 5 );
 vector vector3 = new vector( 2, 2 );
 console.writeline("向量1为( 3, 4 ) \t 向量2为( 0, 5 ) \t 向量3为( 2, 2 )");
 console.writeline("向量1 == 向量2 为：{0}", vector1 == vector2 );
 console.writeline("向量1 != 向量2 为：{0}", vector1 != vector2 );
 console.writeline("向量1 > 向量3 为：{0}", vector1 > vector3 );
 console.writeline("向量2 < 向量3 为：{0}", vector2 < vector3 );
 console.writeline("向量1 >= 向量2 为：{0}", vector1 != vector2 );
 console.writeline("向量1 <= 向量2 为：{0}", vector1 != vector2 );
 }
}
