C# 向应用程序传递参数

有时候使用不同的程序编写不同的模块，相互间少不了要传递个参数啊什么的。本程序示例简单说明如何向C#应用程序传递参数。

    Program.cs中的代码如下：

using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace 参数调用Test
{
    public class ARG
    {
        static string abc;
        public void Arr(string[] a)
        {
            if (a.Length == 0)
            {
                //MessageBox.Show("nothing");测试时使用
                abc = "nothing";//此处可以自行设置
            }
            else
            {
                for (int i = 0; i < a.Length; i++)
                {
                    abc = abc+a[i];
                }
                //MessageBox.Show(abc.Length.ToString() );测试时使用
            }
        }
        public string getContent()
        {
            string k = "";
            k = abc;
            return k;
        }
    }
    static class Program
    {
        ///

        /// 应用程序的主入口点。
        ///

        [STAThread]

        static void Main(string[] args)
        {
            ARG a = new ARG();
            a.Arr(args);
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
}

    Form1.cs的代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace 参数调用Test
{
    public partial class Form1 : Form
    {
        ARG a = new ARG();
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.Close();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            ARG a = new ARG();
            string bb = a.getContent();
                textBox1.Text = bb;
        }
    }
}

    Form1.Designer.cs的代码如下：

namespace 参数调用Test
{
    partial class Form1
    {
        ///

        /// 必需的设计器变量。
        ///

        private System.ComponentModel.IContainer components = null;

        ///

        /// 清理所有正在使用的资源。
        ///

        /// 如果应释放托管资源，为 true；否则为 false。
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows 窗体设计器生成的代码

        ///

        /// 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。
        ///

        private void InitializeComponent()
        {
            this.button1 = new System.Windows.Forms.Button();
            this.textBox1 = new System.Windows.Forms.TextBox();
            this.SuspendLayout();
            // 
            // button1
            // 
            this.button1.Location = new System.Drawing.Point(364, 24);
            this.button1.Name = "button1";
            this.button1.Size = new System.Drawing.Size(73, 33);
            this.button1.TabIndex = 0;
            this.button1.Text = "END";
            this.button1.UseVisualStyleBackColor = true;
            this.button1.Click += new System.EventHandler(this.button1_Click);
            // 
            // textBox1
            // 
            this.textBox1.Location = new System.Drawing.Point(12, 12);
            this.textBox1.Multiline = true;
            this.textBox1.Name = "textBox1";
            this.textBox1.ScrollBars = System.Windows.Forms.ScrollBars.Vertical;
            this.textBox1.Size = new System.Drawing.Size(317, 67);
            this.textBox1.TabIndex = 1;
            // 
            // Form1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(491, 91);
            this.Controls.Add(this.textBox1);
            this.Controls.Add(this.button1);
            this.Name = "Form1";
            this.Text = "Form1";
            this.Load += new System.EventHandler(this.Form1_Load);
            this.ResumeLayout(false);
            this.PerformLayout();

        }

        #endregion

        private System.Windows.Forms.Button button1;
        public System.Windows.Forms.TextBox textBox1;
    }
}
