broadcast方法不再駐留在Program類中。它現在是Form1類的內部，所以從在的Winforms程序更改線104的代碼：

Program.broadcast(dataFromClient, clNo, true);

到

Form1.broadcast(dataFromClient, clNo, true);

（代碼可以在handleClinet找到=>doChat =>while = >try）

更新基於意見從Steve：

你的「錯誤」大多是警告，但只有1是錯誤。

警告，您的代碼編譯和工作，但編譯器是「警告」你，你做的事情是不是真的正確/應該改變，如果可能的話。

錯誤確實需要修復。所以當你發佈所有「錯誤」時，你實際上只發布了1個錯誤和4個警告。

如果代碼正常並且我的答案解決了您的問題，請將其標記爲已接受，然後請他/她通過編譯器瞭解警告和錯誤消息之間的區別 – Steve

thx它正在工作 – fastaykoo

@fastaykoo。這向社區表明，答案是正確的（如果其他人有類似的問題並且遇到您的問題）。有關更多信息，請參閱：http://stackoverflow.com/help/someone-answers。 – SynerCoder
