How to get string's width

Edit

Graphics is from a Pdf in memory, but I am not sure how to use that with Graphics class... Not sure what's e in this answer Get System.Drawing.Font width?

First Question

Trying to get string's width using this method,

    public static void GetStringWidth(string measureString)
    {
        Font stringFont = new Font("Arial", 16);
        SizeF stringSize = new SizeF();
        stringSize = Graphics.MeasureString(measureString, stringFont);
        double width = stringSize.Width;

        Console.WriteLine(width);
    }

But getting error,

An object reference is required for the non-static field, method, or property 'System.Drawing.Graphics.MeasureString(string, System.Drawing.Font)'

MeasureString is not a static method. You will need to use a Graphics instance to access it.

For example:

private void MeasureString(PaintEventArgs e)
{
    string measureString = "Measure String";
    Font stringFont = new Font("Arial", 16);
    SizeF stringSize = new SizeF();
    stringSize = e.Graphics.MeasureString(measureString, stringFont);
}

If you are referencing System.Windows.Forms use the TextRenderer class instead, this will relieve you of having a Graphics object.

private void MeasureText()
{
    String text1 = "Some Text";
    Font arialBold = new Font("Arial", 16);
    Size textSize = TextRenderer.MeasureText(text1, arialBold);
}

UPDATE:

You can use a fake image to measure a string using Graphics as we cannot use CreateGraphics in a class library:

private void MeasureString()
{
    string measureString = "Measure String";
    Font font = new Font("Arial", 16);
    Image fakeImage = new Bitmap(1,1); 
    Graphics graphics = Graphics.FromImage(fakeImage);
    SizeF size = graphics.MeasureString(measureString, font);
}
