C# extention extension

class

public static class 任意类名1
{
    public static string 任意方法名1(this <T>  plugins,....)
    {
        return "只要命名空间有引用，<T>  的类型能匹配到，这个扩展就可用，真方便";
    }
}

比如

1: public static class AnyName
2: {
3:     public static string GetMyName1(this string thisval)
4:     {
5:         return "只要命名空间有引用，<T>  的类型能匹配到，这个扩展就可用，真方便";
6:     }
7: }
8:
9: string sss = "";
0: string sss1 = sss.GetMyName1();

再如

1: public static class AnyName123
2: {
3:     public static string  Getval(this int thisval)
4:     {
5:         return thisval.Tostring();
6:     }
7: }
8:
9: int sss = 0;
0: string  sss1 = sss.Getval();
