C# 如何使变量可以从类的每个方法访问？

我有一个名为“mode”的int。我想让每个函数都能访问它

这是我的密码

namespace WindowsFormsApplication1
{
    public partial class Form5 : Form
    {
        public Form5()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            int wow = mode - 1;
        }

        private void Form5_Load(object sender, EventArgs e)
        {
            int mode = 4;
        }
    }
}

然而，如果没有一页关于这一点的文章，我会感到惊讶。此外，我还建议您查看MSDN和其他c#.net编程资源

只需将其作为类的属性即可

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

namespace WindowsFormsApplication1
{
public partial class Form5 : Form
{
    public int mode {get; set;}
    public Form5()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        int wow = mode - 1;
    }

    private void Form5_Load(object sender, EventArgs e)
    {
        mode = 4;
    }
}
}

这真的是编程101。我建议您查看如何创建对象。在它前面写“public”，我们不会对此问题提供任何解释-没有帮助。您应该在Form5_Load中从赋值中删除

int

，否则它将隐藏属性。

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

namespace WindowsFormsApplication1
{
public partial class Form5 : Form
{
    public int mode {get; set;}
    public Form5()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        int wow = mode - 1;
    }

    private void Form5_Load(object sender, EventArgs e)
    {
        mode = 4;
    }
}
}
