编程学习网为您整理以下代码实例，主要实现：C#泛型方法，希望可以帮到各位朋友。

using System;
using System.Collections.Generic;

namespace GenericmethodAppl {

   class Program {

      static voID Swap<T>(ref T lhs, ref T rhs) {
         T temp;
         temp = lhs;
         lhs = rhs;
         rhs = temp;
      }

      static voID Main(string[] args) {
         int a, b;
         char c, d;
         a = 10;
         b = 20;
         c = 'I';
         d = 'V';

         //display values before swap:
         Console.Writeline("Int values before calling swap:");
         Console.Writeline("a = {0}, b = {1}", a, b);
         Console.Writeline("Char values before calling swap:");
         Console.Writeline("c = {0}, d = {1}", c, d);

         //call swap
         Swap<int>(ref a, ref b);
         Swap<char>(ref c, ref d);

         //display values after swap:
         Console.Writeline("Int values after calling swap:");
         Console.Writeline("a = {0}, b = {1}", a, b);
         Console.Writeline("Char values after calling swap:");
         Console.Writeline("c = {0}, d = {1}", c, d);

         Console.ReadKey();
      }
   }
}
