推荐答案

不确定将适用于Web应用程序...只需尝试

Not sure if it will works for web application...just try

Directory.SetCurrentDirectory(Environment.GetFolderPath(Environment.SpecialFolder.Desktop));

不确定我是否理解您的问题，但是如果您要将文件复制到本地目录，那么可能会有所帮助.详细说明您的问题.

not sure I understand your problem, but if you are looking for copying the file to your local directory,then probably this would help. Elaborate your question.

BinaryReader sr = new BinaryReader(this.FileUpload1.FileContent);
FileStream fs = new FileStream(@"C:\" + FileUpload1.FileName, FileMode.Create);
BinaryWriter sw = new BinaryWriter(fs);
//sw.Write(WriteLine(sr.ReadToEnd());
byte[] b = new byte[1024];
int index = 0;
int i;
while ((i = sr.Read(b, 0, 1024)) > 0)
{
    sw.Write(b);
    index += i;
}
//fs.Close();
sw.Flush();
sw.Close();
fs.Close();

由于未明确询问您的问题，我假设您想要的是诸如SaveDialog之类的东西，可以在Winforms中访问，但不能在Web中访问.您可以查看这些链接，以如何拥有自己的另存为"对话框；

Since your question is not clearly asked I am assuming you want something like SaveDialog which can be accessible in winforms but not in web. You can check out these links how you can have your own Save As Dialog Box;
