如何在VB.NET中设置线条的粗细

Imports System.Drawing

Public Class Form1
    Private Sub Form1_Paint(sender As Object, e As PaintEventArgs) Handles MyBase.Paint
        ' 创建一个Pen对象，设置颜色为红色，粗细为3
        Dim redPen As New Pen(Color.Red, 3)

        ' 绘制一条线
        e.Graphics.DrawLine(redPen, 50, 50, 200, 100)
    End Sub
End Class
