文本

要在表单上绘制文本，请使用 DrawString 方法

绘制字符串时，可以使用上面列出的 4 种画笔中的任何一种

Dim lBrush As New LinearGradientBrush(point1, point2, Color.MediumVioletRed, Color.PaleGreen)
e.Graphics.DrawString("HELLO", New Font("Impact", 60, FontStyle.Bold), lBrush, New Point(40, 400))
'this will draw the word "Hello" at the given point, with a linearGradient Brush

由于无法定义文本的宽度或高度，请使用 Measure Text 来检查文本大小

Dim lBrush As New LinearGradientBrush(point1, point2, Color.MediumVioletRed, Color.PaleGreen)
Dim TextSize =  e.Graphics.MeasureString("HELLO", New Font("Impact", 60, FontStyle.Bold), lBrush)
'Use the TextSize to determine where to place the string, or if the font needs to be smaller

例如：你需要在表单顶部绘制测试一词。表单的宽度为 120.使用此循环减小字体大小，直到它适合表单宽度

Dim FontSize as Integer = 80
Dim TextSize = e.graphics.measeString("Test", New Font("Impact",FontSize, FontStyle.Bold), new Brush(colors.Blue, 10)    
Do while TextSize.Width >120
FontSize = FontSize -1
TextSize = e.graphics.measeString("Test", New Font("Impact",FontSize, FontStyle.Bold), new Brush(colors.Blue, 10)  
Loop
