当前上下文中不存在名称“xx" [英] The name 'xx' does not exist in the current context

问题描述

不太确定我做错了什么.我得到的错误是:

Not quite sure what I'm doing wrong. The errors I'm getting are:

名称_questions"在当前上下文中不存在 - FormChoose.cs

The name '_questions' does not exist in the current context - FormChoose.cs

代码:

FormChoose.cs

FormChoose.cs

using System;
using System.IO;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Xml.Linq;
using System.Xml.Serialization;

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

        private void button1_Click(object sender, EventArgs e)
        {
            _questions = GetQuestions("1");
        }
    }
}

Form1.cs

using System;
using System.IO;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Xml.Linq;
using System.Xml.Serialization;

推荐答案

您正试图从未声明的位置访问成员和方法.您尝试访问的方法和成员(_questions 和 GetQuestions())是 Form1 的一部分，并且您正在尝试在 FormChoose 中访问它们.唯一的方法是在FormChoose 中引用一个Form1 对象.而且我真的没有看到您在 Form1 中声明 path 应该是什么.

You're trying to access members and methods from a location where they aren't declared. The method and member you're trying to access (_questions and GetQuestions()), are part of Form1, and you're trying to access them in FormChoose. The only way to do that, is to have a reference to a Form1 object in FormChoose. And I'm not really seeing anywhere where you are declaring what path is supposed to be in Form1.
