无法从另一个 class c# 调用变量

Unable to call a variable from another class c#

我的 C# 应用程序中有以下 class:

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 都有适当的值。 在我的 Form1.Designer 中,我想调用这些详细信息以显示在表单上(button1 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);

但是

但我看到这个错误: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?)

仅使用 sessName 时也会失败 - 谁能给我指出正确的方向?

非常感谢

解决办法是在创建的时候将需要的值传给Form1。例如,假设您想要访问 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);
