FileIOPermission in WebSite

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();

It's my code ..and I run on server getting me this error

System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed....

Please solve this error......

Simple: you don't have the permission to access one of those files and/or directories. We can't solve this - you have to solve it yourself! Debug through your code - where exactly does this error happen, what line?? — marc_s

Check Your hosting panel and changes permission of IIS user on your upload image folder.

Happy Coding :)
