解决方案

首先，您需要你可以通过在字符串前加一个@，或者加双反斜杠来实现。

  FileUpload1.SaveAs（@C：\ Users \Vinay\Documents\Visual Studio 2010\WebSites\Onlinedoctorsportal\vini+ FileUpload1 。文件名）; 
  

OR

  FileUpload1.SaveAs（C：\\ Users \\\\\\\\\\\\\\\\\\\\\\\\\\\\ FileUpload1.FileName）;其次，请检查您的ASP.NET应用程序池进程正在运行的用户是否有权写入其他用户到指定的文件夹。
 
 
快速检查这是否是问题，是在您的web.config文件中模拟您的本地管理员帐户。
 
 
 
您可以通过配置impersonate标记来完成此操作，如下所示： 
 
 
 < identity impersonate = true
 userName =domain\user
 password =password/> 
  
 
if (FileUpload1.HasFile)
            try
            {
                FileUpload1.SaveAs("C:\\Users\\Vinay\\Documents\\Visual Studio 2010\\WebSites\\Onlinedoctorsportal\\vini" +
                     FileUpload1.FileName);
                Label10.Text = "File name: " +
                     FileUpload1.PostedFile.FileName + "<br>" +
                     FileUpload1.PostedFile.ContentLength + " kb<br>" +
                     "Content type: " +
                     FileUpload1.PostedFile.ContentType;
            }
            catch (Exception ex)
            {
                Label10.Text = "ERROR: " + ex.Message.ToString();
            }
        else
        {
            Label10.Text = "You have not specified a file.";
        }
           //Stream obj = FileUpload1.FileContent;
           //Session["file"] = obj;
           //Response.Redirect("Form3.aspx");
        }
}
what i want is to save the uploaded file to a folder named vini but it is showing the file but not saving it to the specified folder as shown please help
 解决方案 
Firstly you need to escape your string literal that points to the directory
You can do this by adding an @ before the string, or by putting double backslashes.
FileUpload1.SaveAs(@"C:\Users\Vinay\Documents\Visual Studio 2010\WebSites\Onlinedoctorsportal\vini" + FileUpload1.FileName);
OR
FileUpload1.SaveAs("C:\\Users\\Vinay\\Documents\\Visual Studio 2010\\WebSites\\Onlinedoctorsportal\\vini" + FileUpload1.FileName);
Secondly, check that the user that your ASP.NET application pool process is running under has permissions to write to the specified folder.
A quick check to see if this is the problem is to impersonate your local admin account in your web.config file.
You can do this by configuring the impersonate tag as follows:
<identity impersonate="true"
      userName="domain\user"
      password="password" />
