如何在自定义的控件中使用输入法

1.需要将Control.ImeMode设置为On
2.处理OnKeyPress

        public class EditorControl : System.Windows.Forms.Control
        {
            public EditorControl()
            {
                //开启输入法模式
                this.ImeMode = System.Windows.Forms.ImeMode.On;
            }

            protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
            {
                base.OnPaint(e);
                //将Text显示出来
                System.Windows.Forms.TextRenderer.DrawText(e.Graphics,
                    this.Text,
                    new System.Drawing.Font("微软雅黑",30),
                    new System.Drawing.Point(0,0),
                    System.Drawing.Color.Black);
            }

            protected override void OnKeyPress(System.Windows.Forms.KeyPressEventArgs e)
            {
                base.OnKeyPress(e);
                this.Text += e.KeyChar;
                this.Invalidate();
                e.Handled = true;//注意这里，如果这里没设置，输入中文会重复。
            }
        }
