如何将变量从一个 class 引用到另一个？

Question

我是 C# 的新手，我不知道如何将变量的值从一个 class 引用到另一个。

它设置为按下按钮时，它将获取文本框中的文本并将其设置为“alphaask”。 然后它实例化“alphaanswer”，它会告诉 label 更改其文本。

“alphaanswer” 将取值“alphaQuest”，看看它是否等于“bob”，这将改变 label。

所有我想知道如何从“alphaask”的值中设置“alphaQuest”的值，以便字符串可以用“alphaanswer”检查它

public partial class QuestionTab : Form
{
    public string alphaask = "null";

    public void button1_Click(object sender, EventArgs e)
    {
        // alphabutton
        // Checks if something is in textbox then says bool is true
        bool asked = false;
        if(textBoxAlpha.Text != "")
        {
            alphaask = textBoxAlpha.Text;
            asked = true;
        }

        if(asked==true)
        {

            // If bool is true than instance auxy
            var instance = new Alpha();
            instance.alphaanswer();

        }
    }
}

public class Alpha
{
    string alphaQuest = // <-- I want to make alphaQuest equal to alphaask

    alphaanswer();

    public void alphaanswer()
    {
        if (alphaanswer == bob)
         {
          //change text in label1
         }
        }
    }

做这些改变

public partial class QuestionTab : Form
{
    public string alphaask = "null";

    public void button1_Click(object sender, EventArgs e)
    {
        bool asked = false;
        if(textBoxAlpha.Text != "")
        {
            alphaask = textBoxAlpha.Text;
            asked = true;
        }

        if(asked==true)
        {

            // If bool is true than instance auxy
            var instance = new Alpha();
            instance.alphaAnswer(alphaask); 
            //Here you are sending the current value of alphaAsk to the alphaanswer method.
        }
    }
}


public class Alpha
{
    public void alphaAnswer(string alphaAnswer) //This string receives the value you sent
    {
        if (alphaAnswer == "bob")
         {
          //change text in label1
         }
    }
}

Answer 2

使用字符串参数在 class Alpha 中创建一个承包商

public Alpha(String value)
{
}

那么当你调用它时

var instance = new Alpha(alphaask);
instance.show();
