C#特殊類型窗體制作:制作字形窗體

原理:重寫當前窗體 OnPaint 方法, 如下:

protected override void OnPaint(PaintEventArgs e)
{
e.Graphics.DrawImage((Image)bit, new Point(0, 0));
}

一.窗體設計:

#region Windows 窗體設計器生成的代碼

/// <summary>
/// 設計器支持所需的方法 - 不要
/// 使用代碼編輯器修改此方法的內容。
/// </summary>
private void InitializeComponent()
{
this.label1 = new System.Windows.Forms.Label();
this.SuspendLayout();
//
// label1
//
this.label1.BackColor = System.Drawing.Color.Transparent;
this.label1.Location = new System.Drawing.Point(261, 56);
this.label1.Name = "label1";
this.label1.Size = new System.Drawing.Size(17, 16);
this.label1.TabIndex = 0;
this.label1.Click += new System.EventHandler(this.label1_Click);
//
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.BackColor = System.Drawing.SystemColors.Control;
this.ClientSize = new System.Drawing.Size(393, 317);
this.Controls.Add(this.label1);
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.Name = "Form1";
this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
this.Text = "非矩形窗體";
this.TransparencyKey = System.Drawing.SystemColors.Control;
this.Load += new System.EventHandler(this.Form1_Load);
this.ResumeLayout(false);
}
#endregion

二.代碼控制

public partial class Form1 : Form
{
Bitmap bit;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
bit = new Bitmap("wordImage.bmp");
bit.MakeTransparent(Color.Blue);
}
protected override void OnPaint(PaintEventArgs e)
{
e.Graphics.DrawImage((Image)bit, new Point(0, 0));
}
private void label1_Click(object sender, EventArgs e)
{
this.Close();
}
}
