{
System.Drawing.Graphics graphics = textbox.CreateGraphics();
var characterWidth = (int)graphics.MeasureString("M", textbox.Font).Width;

}示例2: CreateTextBox
/// <summary>
/// Returns a default TextBox.
/// Its position is based on both parameters.
/// </summary>
/// <param name="position">Position of the TextBox.</param>

{
TextBox txt = new TextBox();
txt.Multiline = false;
StringBuilder sb = new StringBuilder(reqWidth < 0 ? 0 : reqWidth);
for (int i = 0; i < reqWidth; i++)
sb.Append("o"); // take 'o' as the character to measure
int width = (int)(txt.CreateGraphics().MeasureString(sb.ToString(), txt.Font).Width);
if (width < position.WidthColumnTwo)
{
txt.Width = position.WidthColumnTwo;
txt.Location = new Point(position.StartColumnTwo, position.LinePosition - 5);
}
