我有一个 Web 设置项目。在设置中，我有一个输入字段，用户可以在其中插入连接字符串。当我运行设置时，我收到此错误：
错误 1001。未知错误 (0x8000x5000)
为了跟踪错误存在的位置，我创建了一个文件，并在每种方法中都向该文件写入了一些内容。现在我认为这一行引发了错误：
string friendlySiteName = entry.Properties["ServerComment"].Value.ToString();
但我不知道如何纠正这个问题。我希望你能帮帮我！
代码：
public override void Install(System.Collections.IDictionary stateSaver)
{
base.Install(stateSaver);

StreamWriter w = new StreamWriter(f);
w.WriteLine("targetSite: " + targetSite);
w.WriteLine("targetVDir: " + targetVDir);
w.WriteLine("targetDirectory: " + targetDirectory);
w.WriteLine("targetConnectionString: " + targetConnectionString);
w.Close();
w.Dispose();
f.Close();
f.Dispose();
ConfigureWebConfig(targetSite, targetVDir, targetConnectionString);
}
