小弟最近在研究委托和接口,有点不明白的地方希望各位前辈给点指导,先谢谢了
是这样,我写了一个最简单的委托,然后想写一个接口来实现。using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;namespace consign1
{
/// <summary>
/// Form1 的摘要说明。
/// </summary>
//定义一个接口
interface consign //接口
{
} //定义一个委托
public delegate int text(int x,int y); public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1;
private System.Windows.Forms.TextBox textBox1;
private System.Windows.Forms.TextBox textBox2;
private System.Windows.Forms.TextBox textBox3;
private System.Windows.Forms.Label label1;
private System.Windows.Forms.Button button2;
/// <summary>
/// 必需的设计器变量。
/// </summary>
private System.ComponentModel.Container components = null; public Form1()
{
//
// Windows 窗体设计器支持所必需的
//
InitializeComponent(); //
// TODO: 在 InitializeComponent 调用后添加任何构造函数代码
//
} /// <summary>
/// 清理所有正在使用的资源。
/// </summary>
protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
} static int text1(int e,int r)
{
return e*r;
} #region Windows 窗体设计器生成的代码
/// <summary>
/// 设计器支持所需的方法 - 不要使用代码编辑器修改
/// 此方法的内容。
/// </summary>
private void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
this.textBox1 = new System.Windows.Forms.TextBox();
this.textBox2 = new System.Windows.Forms.TextBox();
this.textBox3 = new System.Windows.Forms.TextBox();
this.label1 = new System.Windows.Forms.Label();
this.button2 = new System.Windows.Forms.Button();
this.SuspendLayout();
//

//
this.button1.Location = new System.Drawing.Point(16, 80);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(96, 23);
this.button1.TabIndex = 0;
this.button1.Text = "=";
this.button1.Click += new System.EventHandler(this.button1_Click);
//

this.textBox3.Location = new System.Drawing.Point(16, 136);
this.textBox3.Name = "textBox3";
this.textBox3.Size = new System.Drawing.Size(240, 21);
this.textBox3.TabIndex = 1;
this.textBox3.Text = "";
//

this.label1.Location = new System.Drawing.Point(128, 40);
this.label1.Name = "label1";

this.Name = "Form1";
this.Text = "Form1";
this.Load += new System.EventHandler(this.Form1_Load);
this.ResumeLayout(false); }
#endregion /// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main()
{
Application.Run(new Form1());
} private void Form1_Load(object sender, System.EventArgs e)
{
} private void button1_Click(object sender, System.EventArgs e)
{
int a = Convert.ToInt32(textBox1.Text);
int b = Convert.ToInt32(textBox2.Text);
text t1 = new text(text1); int temp = t1(a,b);
textBox3.Text = temp.ToString();
} private void button2_Click(object sender, System.EventArgs e)
{
textBox1.Text = "";
textBox2.Text = "";
textBox3.Text = "";
}
}
}
问题就是在接口中我应该写什么呢?我想把委托的方法
static int text1(int e,int r)
{
return e*r;
}
写到接口中,然后再用一个类来继承接口,但是在实现接口的时候就不知道怎么写了,如果要是这么写的话,那么委托应该传什么参呢?拜托前辈指点一二,谢谢了~
