将click方法的(继承)值传递给其他表单方法? [英] Passing (Inheritance) values from click Method to other form methods?

问题描述

你好，

自编写程序以来已经很长时间了，但是我决定要学习C#...

我正在编写一个具有某些字段的Windows窗体应用程序.这些字段用于定义多维数组的大小.表单用户输入字段并单击设置值"按钮后，其余的表单按钮将变为可用.

问题，如果要在setvalues_click方法内部创建数组，如何在方法之间传递数组?

Hello,

It has been a long time since I wrote a program but I decided that I want to learn C#...

I am writting a Windows Form application that has some fields. These fields are used to define the size of an multi-dimensional array. Once the fields are input by the form user and the set value button is clicked, the rest of the forms buttons become available.

Question, how do I pass the array from method to method, if I am creating the array inside of the setvalues_click method?

namespace WFRobotCar
 {
 private void Setvalue_Click(object sender, EventArgs e)
    {
       Myrc array_rc = new Myrc(Convert.ToInt32(this.XtextBox.Text), Convert.ToInt32(this.YtextBox.Text));
    }

 private void printrc_click(object sender, EventArgs e)
    {
      int i, j;
      for (int i = 0; i < array_rc.GetLength(0); i++)
        {
            Console.Write("     ");
            for (int j = 0; j < array_rc.GetLength(1); j++)
            {
                if ((i == int_current_row) && (j == int_current_col))
                    Console.ForegroundColor = ConsoleColor.Green;
                if (array_rc[i, j])
                {
                    Console.Write('-');
                }
                else
                {
                    Console.Write('0');
                }
                if ((i == int_current_row) && (j == int_current_col))
                    Console.ResetColor();
            }
            Console.WriteLine();
        }

    }
 }

在此先谢谢您，

推荐答案

只需将array全局化为表单并继续.实际上，我会使用List而不是数组，因为List可以按需增长/缩小.

Just make the array global to the form and get on with it. In fact, I would use a List instead of an array because a List can grow/shrink on demand.

这可以是一种解决方案:

This can be a solution :

namespace WFRobotCar
 {
     Myrc array_rc;

 private void Setvalue_Click(object sender, EventArgs e)
    {
       array_rc = new Myrc(Convert.ToInt32(this.XtextBox.Text), Convert.ToInt32(this.YtextBox.Text));
    }
 private void printrc_click(object sender, EventArgs e)
    {
      int i, j;
      for (int i = 0; i < array_rc.GetLength(0); i++)
        {
            Console.Write("     ");
            for (int j = 0; j < array_rc.GetLength(1); j++)
            {
                if ((i == int_current_row) && (j == int_current_col))
                    Console.ForegroundColor = ConsoleColor.Green;
                if (array_rc[i, j])
                {
                    Console.Write('-');
                }
                else
                {
                    Console.Write('0');
                }
                if ((i == int_current_row) && (j == int_current_col))
                    Console.ResetColor();
            }
            Console.WriteLine();
        }
    }
 }

private void Setvalue_Click(object sender, EventArgs e)
{
   Myrc array_rc = new Myrc(Convert.ToInt32(this.XtextBox.Text), Convert.ToInt32(this.YtextBox.Text));

   MyMethod(array_rc)
}


void MyMethod(MyRC arrayIn)
{
// use the array here
}

也许买一本C#书来学习这些基本知识?

Maybe buy a C# book to learn this basic stuff?
