从Windows窗体上的文本框中获取数据

Question

我正在使用Visual Studio创建Windows窗体。我正在为大学的作业制作基于文本的生存游戏，但是我被卡住了。

我的目标是让用户在textbox中输入一个选项（1-4）来做出选择。

我尝试使用4不同的按钮，但似乎无法得到一个if语句来处理按钮点击。然后，我尝试了一个带按钮的开关，然后是一个带有文本的开关，现在带有if/else if语句的文本框。

这里是我的代码：

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
using Microsoft.VisualBasic; 


namespace PF5 
{ 
public partial class Form1 : Form 
{ 

    int iScore = 0, iChoice; 
    String sName; 

    public Form1() 
    { 
     //asks user to input their name before the game begins 
     sName = Microsoft.VisualBasic.Interaction.InputBox("Please enter your name:", "What is Your Name?", ""); 
     //if no name is entered, they are asked again 
     while (sName == "") 
     { 
      MessageBox.Show("Please enter your name."); 
      sName = Microsoft.VisualBasic.Interaction.InputBox("Please enter your name:", "What is Your Name?", ""); 
     } 


     InitializeComponent(); 
    } 

    private void Form1_Load(object sender, EventArgs e) 
    { 
     //displays the score 
     lblScore.Text = iScore.ToString(); 
     //displays the scoring system in the Rules textbox 
     txtRules.Text = "Welcome to SURVIVE, " + sName + ", during your time here you will be presented with numerous scenarios and you will be given FOUR options or choices." + Environment.NewLine + "" + Environment.NewLine + "For each Scenario there will be: " + Environment.NewLine + "" + Environment.NewLine + "ONE 'Perfect Answer' which will give you +2 points to your score. " + Environment.NewLine + "" + Environment.NewLine + "ONE 'Correct Answer' which will award you +1 point to your total. " + Environment.NewLine + "" + Environment.NewLine + "ONE 'Wrong Answer' which will award you +0 points." + Environment.NewLine + "" + Environment.NewLine + "ONE 'Fatal Answer' which will result in Game Over, Death and -1 point."; 
    } 


    private void btnExit_Click(object sender, EventArgs e) 
    { 
     // Display a message box asking users if they 
     // want to exit the application. 
     if (MessageBox.Show("Do you want to exit?", "SURVIVE", 
     MessageBoxButtons.YesNo, MessageBoxIcon.Question) 
     == DialogResult.Yes) 
     { 
      Application.Exit(); 
     } 
    } 

    private void btnStart_Click(object sender, EventArgs e) 
    { 

     //Displays story and Options for the user 
     txtStory.Text = "After a heavy night in town, you wake up the following day with the worst headache ever. The night seems to be a blur. The usual business of outside seems to be quiter than normal, even for a Sunday, but you don't think too much about it." + Environment.NewLine + " After you have had a shower, a coffee and got ready you feel slightly better, you turn on the TV to watch your favorite channel, only to see some pandemic on the news, apparently a ZOMBIE OUTBREAK!" + Environment.NewLine + "Luckily for you though, you have played Black Ops Zombies and Minecraft for most of your student life so you know exactly what to do..." 
      + Environment.NewLine + "" + Environment.NewLine + "Option 1: Run outside and ask the first person you see to help you" + Environment.NewLine + "" + Environment.NewLine + "Option 2: Take some time to get some food and money together and pack them along with extra clothes into your bag." + Environment.NewLine + "" + Environment.NewLine + "Option 3: Text your friends and see if they are okay." + Environment.NewLine + "" + Environment.NewLine + "Option 4: Call the police to let them know a Zombie Outbreak is happening"; 
     btnStart.Visible = false; 

      txtChoice.Text = Convert.ToString(iChoice); 
      iChoice = Convert.ToInt32(Console.ReadLine()); 
      if (iChoice == 1) 
      { 
        txtResult.Text = "You run outside and grab the first person you see by the shoulder, apparently this particular person just wanted to chomp on your flesh." + Environment.NewLine + "" + Environment.NewLine + "YOU DIED!!!"; 
        iScore = -1; 
        lblScore.Text = iScore.ToString(); 
      } 
    } 
} 
} 

我希望有人可以提供帮助。我很高兴与其余的，只是如果声明atm，它只是不会检测textbox中的条目，我也想使用提交答案按钮，但我不知道如何得到它的工作。

只是值得一提的，我不是一个高级用户（如你可能知道）

Answer 1

，我看到您使用的文本框和按钮窗口的形式，但你正在阅读从控制台iChoice。如果你有textBox中的变量（iChoice），那么这种方法试试这个iChoice = Int32.Parse(iChoiceTextBox.Text);

变化btnStart_click事件：

private void btnStart_Click(object sender, EventArgs e) 
    { 

     //Displays story and Options for the user 
     txtStory.Text = "After a heavy night in town, you wake up the following day with the worst headache ever. The night seems to be a blur. The usual business of outside seems to be quiter than normal, even for a Sunday, but you don't think too much about it." + Environment.NewLine + " After you have had a shower, a coffee and got ready you feel slightly better, you turn on the TV to watch your favorite channel, only to see some pandemic on the news, apparently a ZOMBIE OUTBREAK!" + Environment.NewLine + "Luckily for you though, you have played Black Ops Zombies and Minecraft for most of your student life so you know exactly what to do..." 
      + Environment.NewLine + "" + Environment.NewLine + "Option 1: Run outside and ask the first person you see to help you" + Environment.NewLine + "" + Environment.NewLine + "Option 2: Take some time to get some food and money together and pack them along with extra clothes into your bag." + Environment.NewLine + "" + Environment.NewLine + "Option 3: Text your friends and see if they are okay." + Environment.NewLine + "" + Environment.NewLine + "Option 4: Call the police to let them know a Zombie Outbreak is happening"; 
     btnStart.Visible = false; 

     iChoice = Int32.Parse(txtChoice.Text); 
     if (iChoice == 1) 
     { 
      txtResult.Text = "You run outside and grab the first person you see by the shoulder, apparently this particular person just wanted to chomp on your flesh." + Environment.NewLine + "" + Environment.NewLine + "YOU DIED!!!"; 
      iScore = -1; 
      lblScore.Text = iScore.ToString(); 
     } 
    }
