Hello..
How I can determine the width and Height for the PostedFile in FileUpload.

Code:

System.Drawing.Image image = System.Drawing.Image.FromFile(filePath);
int height = image.Height;
int width = image.Width;

I used this code

Code:

protected void Button1_Click(object sender, EventArgs e)
    {
         Stream s = FileUpload1.PostedFile.InputStream;   
        Image i= System.Drawing.Image.FromStream(s);   
                      
        intFileWidth = i.PhysicalDimension.Width;   
        intFileHeight = i.PhysicalDimension.Height;  
        
      
    }

but this error occurred

Compiler Error Message: CS0029: Cannot implicitly convert type 'System.Drawing.Image' to 'System.Web.UI.WebControls.Image'

Please Help me.

You need to specify the namespace:

Code:

        Stream stream = FileUpload1.FileContent;
        System.Drawing.Image image = System.Drawing.Image.FromStream(stream);
        Label1.Text = image.Width.ToString();
        Label2.Text = image.Height.ToString();
