Question

我正在尝试将一些代码放在另一个.cs文件中，因为我正在使用它一个巨大的转换声明，我不希望人们趟过它了解发生了什么。问题是txtresponse 描述在我的应用程序中写入的文本框的命令不是在新文件中定义，我无法弄清楚为什么。这是我的新事物档案：

（错误：此当前上下文中不存在txtresponse）

P.S。仅使用System.Windows.Forms;突出显示它包含所有应用程序表单，按钮和他们做什么等...

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

namespace GUI_Verify
{
    class commands : Form
    {
        public static string call_command(string stmnt)
        {
            string cmd = "";
            switch (stmnt)
            {
                case "TST_ALL":
                    txtresponse.Text = "\r\nTesting all memory tests.\r\n";
                    cmd = "1";
                    break;
                case "TST_PKT_BFFR":
                    txtResponse.Text = "\r\nTest for Packet Buffer.\r\n";
                    cmd = "2";
                    break;
                case "TST_XDATA":
                    txtResponse.Text = "\r\nTest for XDATA.\r\n";
                    cmd = "3";
                    break;
                case "TST_REN_RAM":
                    txtResponse.Text = "\r\nTest for Retention Ram.\r\n";
                    cmd = "4";
                    break;
                case "TST_CODE_RAM":
                    txtResponse.Text = "\r\nTest for Code Ram.\r\n";
                    cmd = "5";
                    break;
                case "Copy_All":
                    txtResponse.Text = "\r\nCopying all memory to all places.\r\n";
                    cmd = "6";
                    break;
                case "to_xdata":
                    txtResponse.Text = "\r\nCopying xdata -> xdata.\r\n";
                    cmd = "7";
                    break;
                default:
                    txtResponse.Text = "\r\nunknown command\r\n";
                    break;
            }
            return cmd;
        }
    }
}

我有时会遇到这个问题。首先注释您的代码并删除表单中的txtresponse文本框。然后从工具箱中拖放新的TextBox并将其重命名为“txtresponse”。取消注释您的代码，希望它能够正常工作。

这只是对另一种方式的建议。没有继承Form类

使用输出参数来保存文本框的值。

namespace GUI_Verify
{
    public class commands
    {
        public static string call_command(string stmnt, out string result)
        {
            string cmd = "";
            switch (stmnt)
            {
                case "TST_ALL":
                    result = "\r\nTesting all memory tests.\r\n";
                    cmd = "1";
                    break;
                case "TST_PKT_BFFR":
                    result = "\r\nTest for Packet Buffer.\r\n";
                    cmd = "2";
                    break;
                case "TST_XDATA":
                    result = "\r\nTest for XDATA.\r\n";
                    cmd = "3";
                    break;
                case "TST_REN_RAM":
                    result = "\r\nTest for Retention Ram.\r\n";
                    cmd = "4";
                    break;
                case "TST_CODE_RAM":
                    result = "\r\nTest for Code Ram.\r\n";
                    cmd = "5";
                    break;
                case "Copy_All":
                    result = "\r\nCopying all memory to all places.\r\n";
                    cmd = "6";
                    break;
                case "to_xdata":
                    result = "\r\nCopying xdata -> xdata.\r\n";
                    cmd = "7";
                    break;
                default:
                    result = "\r\nunknown command\r\n";
                    break;
            }
            return cmd;
        }

    }
}

在您的表单中执行以下操作。

string result="";
string cmd = commands.call_command("TST_ALL", out result);
txtresponse.Text = result;
