我用C#编写了一个IP多播应用程序。它编译得很好,但在运行时这一行:sock.SetSocketOption(SocketOptionLevel.IP,SocketOptionName.AddMembership,newMulticastOption(IPAddress.Parse("224.100.0.1")));抛出未处理的套接字异常:Anoperationonasocketcouldnotbeperformedbecausethesystemlackedsufficientbufferspaceorbecauseaqueuewasfull我在Google中搜索错误,有人建议删除可

c# - 使用条件 (? :) operator for method selection in C# (3. 0)?

我正在重构一些代码。现在有很多地方有这样的功能:stringerror;if(a){error=f1(a,long,parameter,list);}else{error=f2(the_same,long,parameter,list);}在重构f1和f2(它们很大,但做类似的事情)之前,我想重构为:stringerror=(a?f1:f2)(a,long,parameter,list);就像在C中所做的那样。(函数签名是相同的)但是我得到一个错误:“错误13无法确定条件表达式的类型,因为‘方法组’和‘方法组’之间没有隐式转换”这将使我能够通过初始重构来识别参数列表是相同的,从而提供不
