How to Check If the image is in the folder in WPF?

Question

In my application i have a textbox from where i can generate image through command in runtime but now i want to check if the image is existing or not.If there is no image then i want to generate a label. here is my code. i was trying to implement it through regular expression.

else if (Regex.IsMatch(label, "^<IMG.*>"))
{
    var imageLabel = Regex.Replace(label, "<IMG|>", "");

    if (System.Drawing.Image.FromFile($"{imageLabel}.bmp") != null)
    {
        var image = System.Drawing.Image.FromFile($"{imageLabel}.bmp");
        graphics.DrawImage(image, x, y, image.Width, image.Height);

        x = image.Width + 5f;

        if (image.Height > rowHeight)
        {
            rowHeight = image.Height;
        }
    }
    else
    {
        var font = GetRowFont(isBold, isUnderLine, isHigh, selectedCharwidth);

        graphics.DrawString("<?>", font, Brushes.Black, new PointF(x, y));

        x += label.Length * font.Size;
    }
}

For example i have an image named ABC.bmp in the folder.So if i type it would generate the image and if there is no image named ABC then it would generate a label ''. It shows an exception if I type wrong name.Sorry for the bad Explanation.

You could modify your code to check if the file exists with the File.Exists method :

 if (File.Exists($"{imageLabel}.bmp"))
 {
    var image = System.Drawing.Image.FromFile($"{imageLabel}.bmp");
    ....
