无法从另一个类c#调用变量

本文关键字:调用 变量 另一个 | 更新日期: 2023-09-27 18:20:33

我的c#应用程序中有以下类:

using System;
using System.Collections.Generic;
using System.Windows.Forms;
namespace Citrix_Killer
{
    public static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        public static void Main()
        {
        string name = Myfunc.userName();
        List<string> servers = Myfunc.get_Servers();
        string[] session = Myfunc.get_Session(servers, name);
        string sessID = session[0];
        string server = session[1]; 
        string sessName = session[2];  
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
        }
    }
}

其中,sessId、server和sessName都具有适当的值。在我的Form1.Designer中,我想调用这些细节来显示在表单上(按钮1的文本):

        // 
        // button1
        // 
        this.button1.Location = new System.Drawing.Point(12, 12);
        this.button1.Name = "button1";
        this.button1.Size = new System.Drawing.Size(75, 23);
        this.button1.TabIndex = 0;
        this.button1.Text = Program.sessName;
        this.button1.UseVisualStyleBackColor = true;
        this.button1.Click += new System.EventHandler(this.button1_Click);

然而

但我看到了这个错误:类型或命名空间名称"sessName"在命名空间"Citrix_Killer"中不存在(您是否缺少程序集引用?)

当只使用sessName时,这也会失败——有人能告诉我正确的方向吗?

非常感谢

无法从另一个类c#调用变量

解决方案是在创建Form1时将所需的值传递给它。例如,假设您希望访问sessIDserversessName,请更改Program.cs:

namespace Citrix_Killer
{
    public static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        public static void Main()
        {
            ...
            Application.Run(new Form1(sessID, server, sessName));
        }
    }
}

并更改Form1.cs以接受其构造函数中的值

public partial class Form1 : Form
{
    private readonly string _sessId;
    private readonly string _server;
    private readonly string _sessName;
    public Form1(string sessId, string server, string sessName)
    {
        _sessId = sessId;
        _server = server;
        _sessName = sessName;
        InitializeComponent();
        ...
    }

然后你可以在你的初始化代码中引用它们:

    // 
    // button1
    // 
    this.button1.Location = new System.Drawing.Point(12, 12);
    this.button1.Name = "button1";
    this.button1.Size = new System.Drawing.Size(75, 23);
    this.button1.TabIndex = 0;
    this.button1.Text = _sessName;
    this.button1.UseVisualStyleBackColor = true;
    this.button1.Click += new System.EventHandler(this.button1_Click);
