这是什么原因啊 --------------------编程问答-------------------- chat1(ns, wo, btn.Text);
没有三个参数的构造函数 --------------------编程问答-------------------- --------------------编程问答-------------------- chat1 myc = new chat1(ns, wo, btn.Text);

意思你的 chat1 类中必须要有一个带3个参数的构造函数声明，可能像下面这样

class chat1
{
   public chat1(NetworkStream n,string str,string str2)
   {
       // ...
   }
}
--------------------编程问答-------------------- 1楼：

可是这怎么怎么写呢？我找到这个原因了，如果把chat1(ns, wo, btn.Text);没有三个参数的构造函数chat1里面的代码删除就没有数据流进行传输了

补充：.NET技术 ,  C#
