这个错误而不是

for this Error Instead of

此行我使用

Directory.Delete(path);

但是agin我得到错误像



错误：

but agin i am getting Error like

Error:

The directory is not empty.

我的尝试：

What I have tried:

public static string ImageToServerPath(student[] student)
       {
           DataImage image = DataImage.TryParse(student[0].path);
           MemoryStream ms = new MemoryStream(image.RawData);
           Bitmap BMP = new Bitmap(image.Image);

           string configPath = WebConfigurationManager.AppSettings["Path"];

           string path =configPath+""+student[0].studentId+"\\";

           if (!Directory.Exists(path))
           {
               Directory.CreateDirectory(path);
           }
           else
           {
               Directory.Delete(path);
               Directory.CreateDirectory(path);
           }

           FileIOPermission writePermission = new FileIOPermission(FileIOPermissionAccess.Write, path);

           if (SecurityManager.IsGranted(writePermission))
           {
               int imagename = 1;
               System.Drawing.Image img = new System.Drawing.Bitmap(ms);
               img.Save(path + student[0].studentId + ".png", ImageFormat.Png);
               path = path + "" + imagename + ".png";
           }
           return path;
       }

推荐答案

我认为你需要关闭 MemoryStream 使用后：

I think you need to close the MemoryStream after using it:

using (MemoryStream ms = new MemoryStream(image.RawData);) 
{  
    BMP = new Bitmap(image.Image);
}

我还要看一下：

I would also take a look at:

DataImage image = DataImage.TryParse(student[0].path);

由于我没有你的源代码，我不知道那里发生了什么......

As I don't have your source code, I can not tell what is happening there ...
