I am getting ther error Invalid length for a Base-64 char array or string while converting base64 to image.

Code:

ImageConvert.cs

public class ImageConvert { string imgStr = "/9j/4AAQSkZJRgABAQEASABIAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQH/2Pp+NKNYLkTRqU2fIRjHIwOP69q1+vU1G1P3XfTS9U8If";

    public Image LoadImage()
    {
        Program obj = new Program();
        Image bmp =  obj.Base64StringToBitmap(imgStr);
       // BitmapImage bmp = Base64StringToBitmap(imgStr);
        //myImage.Source = bmp;
        return bmp;
    }  

}

Program.cs

public class Program { public static void Main() { ImageConvert convert = new ImageConvert(); convert.LoadImage(); }

    public Image Base64StringToBitmap(string base64String)
    {
        Image bmpReturn = null;
        Byte[] bitmapData = new Byte[base64String.Length];
        bitmapData = Convert.FromBase64String(base64String);
        //using(MemoryStream memoryStream = new MemoryStream(sbText))
        //{
        //    memoryStream.Position = 0;
        //    bmpReturn =  System.Drawing.Image.FromStream(memoryStream);
        ////    //BitmapImage bitmapImage = new BitmapImage();
        ////    //bitmapImage.SetSource(memoryStream);

        //   memoryStream.Close();
        ////    //memoryStream = null;
        //    byteBuffer = null;
        ////    //FileStream stream = new FileStream();
        //}
        return bmpReturn; ;
    }
