Question

if (!Directory.Exists(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//OriginalImages"))
{
    Directory.CreateDirectory(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//OriginalImages");
}
if (File.Exists(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//" + fuImageName.FileName.ToString()))
{
    File.Delete(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//" + fuImageName.FileName.ToString());
}
if (File.Exists(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//OriginalImages//" + fuImageName.FileName.ToString()))
{
    File.Delete(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//OriginalImages//" + fuImageName.FileName.ToString());
}
fuImageName.SaveAs(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//" + fuImageName.FileName.ToString());

if (!Directory.Exists(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//ThumbNailImages"))
{
    Directory.CreateDirectory(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//ThumbNailImages");
}

string Path = Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//" + fuImageName.FileName.ToString();
Bitmap bmp1 = CreateThumbnail(Path, 400, 500);

string OutputFilename1 = fuImageName.FileName.ToString();
bmp1.Save(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//OriginalImages//" + OutputFilename1.ToString(), System.Drawing.Imaging.ImageFormat.Jpeg);

bmp1.Dispose();

Bitmap bmp = CreateThumbnail(Path, 100, 100);

string OutputFilename = "Thumb_" + fuImageName.FileName.ToString();
bmp.Save(Request.PhysicalApplicationPath + "Images//Products//" + ddlCategory.SelectedValue.ToString().Trim() + "//" + ProductMasterId.ToString().Trim() + "//ThumbNailImages//" + OutputFilename.ToString(), System.Drawing.Imaging.ImageFormat.Jpeg);

bmp.Dispose();

ClearAll();

这是我的代码..and，我在服务器上运行，得到了这个错误

'System.Security.Permissions.FileIOPermission，System.Security.SecurityException:请求允许输入Version=2.0.0.0，Version=2.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089‘失败.

请解决这个错误.
