C#实现WinForm窗体逐渐显示效果,这个博客园里面已经有其它人已经实现了,原理很简单,就是通过定时改变窗体的透明度(从0到1,即透明度从完全透明到不透明),我这里也是按照这个思路来实现的,但是我做的这个窗体是可复用的,即其它窗体继承自它后,就能实现渐显效果,代码如下:

using System;
using System.ComponentModel;
using System.Windows.Forms;

namespace TEMS.Forms
{
    public partial class FormBase : Form
    {
        private Timer formTimer = null;

        /// <summary>
        /// 获取Opacity属性
        /// </summary>
        [DefaultValue(0)]
        [Browsable(false)]
        public new double Opacity
        {
            get { return base.Opacity; }
            set { base.Opacity = 0; }
        }

        public FormBase()
        {
            InitializeComponent();
            formTimer = new Timer() { Interval = 100 };
            formTimer.Tick += new EventHandler(formTimer_Tick);
            base.Opacity = 0;
        }

        private void formTimer_Tick(object sender, EventArgs e)
        {
            if (this.Opacity >= 1)
            {
                formTimer.Stop();
            }
            else
            {
                base.Opacity += 0.2;
            }
        }

        private void FormBase_Shown(object sender, EventArgs e)
        {
            formTimer.Start();
        }
    }
}

以下是自动生成的代码:

namespace TEMS.Forms
{
    partial class FormBase
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows Form Designer generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            this.SuspendLayout();
            // 
            // FormBase
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(284, 262);
            this.Name = "FormBase";
            this.Text = "FormBase";
            this.Shown += new System.EventHandler(this.FormBase_Shown);
            this.ResumeLayout(false);

        }

        #endregion
    }
}
