帮我看看，为什么我写不进文件啊？

/// <summary>
/// 保存器设置
/// </summary>
/// <param name="ip">IP</param>
/// <param name="prot">端口号</param>
/// <returns></returns>
public static bool SaveConfigServer(string ip,string prot)
{
try
{
StringBuilder strBuilder = new StringBuilder();
string configUrl = "config/ipConfig.dat";
strBuilder.Append("<?xml version=\"1.0\" encoding=\"UTF-8\"?><root><server>");
strBuilder.Append("<ip>"+ip+"</ip>");
strBuilder.Append("<prot>"+prot+"</prot>");
strBuilder.Append("</server></root>");


StreamWriter strWriter = new StreamWriter(configUrl);
strWriter .Write(strBuilder.ToString());
strWriter .Close();
return (true);

}
catch
{
return (false);
}

}

在下新手，请大大们多多指点，帮忙改正。小弟在此谢过额

只能帮顶顶。。。汗，技术有限。。。

路径configUrl在VS的Common7\IDE目录中。。。指定路径错误。。

[jdxx]

string configUrl = "config/ipConfig.dat";

指定有写入权限的绝对路径。

然后改为：

FileStream fs = new FileStream(configUrl, FileMode.Create);
StreamWriter strWriter = new StreamWriter(fs);
strWriter .Write(strBuilder.ToString());
strWriter .Close();
return (true);

写快了，还漏写了：

FileStream fs = new FileStream(configUrl, FileMode.Create);
StreamWriter strWriter = new StreamWriter(fs);

strWriter.Write(strBuilder.ToString());
strWriter.Flush(); //清空缓冲区
strWriter.Close();
fs.Close();

楼上正解~

[birdlonger]

StreamWriter strWriter = new StreamWriter(configUrl,true);
strWriter .Write(strBuilder.ToString());
strWriter.Flush();
strWriter .Close();

5楼正解too
