如何将System.IO.Stream保存为本地文件？
求一下这段代码，谢谢

------解决方案--------------------
public void CreateTextFile(string fileName, string textToAdd)
{
string logFile = DateTime.Now.ToShortDateString()
.Replace(@ "/ ",@ "- ").Replace(@ "\ ",@ "- ") + ".log ";

FileStream fs = new FileStream(fileName,
FileMode.CreateNew, FileAccess.Write, FileShare.None);

StreamWriter swFromFile = new StreamWriter(logFile);
swFromFile.Write(textToAdd);
swFromFile.Flush();
swFromFile.Close();

StreamWriter swFromFileStream = new StreamWriter(fs);
swFromFileStream.Write(textToAdd);
swFromFileStream.Flush();
swFromFileStream.Close();

StreamWriter swFromFileStreamDefaultEnc =
new System.IO.StreamWriter(fs,
System.Text.Encoding.Default);
swFromFileStreamDefaultEnc.Write(textToAdd);
swFromFileStreamDefaultEnc.Flush();
swFromFileStreamDefaultEnc.Close();

StreamWriter swFromFileTrue =
new StreamWriter(fileName,true);
swFromFileTrue.Write(textToAdd);
swFromFileTrue.Flush();
swFromFileTrue.Close();

StreamWriter swFromFileTrueUTF8Buffer =
new StreamWriter(fileName,
true, System.Text.Encoding.UTF8,512);
swFromFileTrueUTF8Buffer.Write(textToAdd);
swFromFileTrueUTF8Buffer.Flush();
swFromFileTrueUTF8Buffer.Close();

StreamWriter swFromFileTrueUTF8 =
new StreamWriter(fileName, true,
System.Text.Encoding.UTF8);
swFromFileTrueUTF8.Write(textToAdd);
swFromFileTrueUTF8.Flush();
swFromFileTrueUTF8.Close();

StreamWriter swFromFileStreamUTF8Buffer =
new StreamWriter(fs, System.Text.Encoding.UTF8, 512);
swFromFileStreamUTF8Buffer.Write(textToAdd);
swFromFileStreamUTF8Buffer.Flush();
swFromFileStreamUTF8Buffer.Close();
}
