Question

我是C＃的新手。我有一个问题，我想在运行时创建名为file的IP地址并将数据写入这些文件。我正在使用此代码，但它不起作用。它让我超越：

First chance exception of type 'System.NotSupportedException' occurred in mscorlib.dll

例外是：

System.NotSupportedException: The given path's format is not supported.

这是我的代码：

System.Diagnostics.Debug.Write( content);
handler.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0,
new AsyncCallback(ReadCallback), state);
System.Diagnostics.Debug.WriteLine(
    "Read {0} bytes from socket. \n Data : {1}", content);


string dir = @"C:\AppRecord";
if (!Directory.Exists(dir))
{
    Directory.CreateDirectory(dir);
}

File.WriteAllText(Path.Combine(dir,
     "log"+handler.RemoteEndPoint.ToString()+".txt"), content);

这是堆栈跟踪：

   at System.Security.Util.StringExpressionSet.CreateListFromExpressions(String[] str, Boolean needFullPath)

   at System.IO.StreamWriter..ctor(String path, Boolean append, Encoding encoding)
   at System.IO.File.WriteAllText(String path, String contents, Encoding encoding)
   at System.IO.File.WriteAllText(String path, String contents)
   at ServerWService.Service1.AsynchronousSocketListener.ReadCallback(IAsyncResult ar)

我认为handler.RemoteEndPoint将返回一个IP地址，其端口由:分隔。但是，Windows上的文件名中不能包含字符:。您将不得不替换其他字符，例如下划线。
