c# 使用 Blocks 外部的字符串对其进行编辑
c# Using strings on the outside of Blocks to edit it
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
string aaxe = null;
string apick = null;
string asho = null;
string acan = null;
string aknife = null;
string akey = null;
string atre = null;
当我点击斧头时(aaxe
)。将 atre
的字符串编辑为 "y" 而不是 null。
但是当我尝试这样做时,它没有在 aaxe
块内找到 atre
。
那我该如何解决呢?
public void Axe_Click(object sender, EventArgs e)
{
if (aaxe == null)
{
richTextBox1.AppendText("You Don't Have An Axe\r\n");
}
if (aaxe == "y")
{
richTextBox1.AppendText("You Used your Axe\r\n");
}
}
这是“atre
”代码
public void Treasure_Click(object sender, EventArgs e)
{
if (atre == null)
{
richTextBox1.AppendText("You Haven't Found the Treasure Yet!\r\n");
string aaxe = "y"
它找不到 aaxe
!
}
if (atre == "y")
{
richTextBox1.AppendText("You Found The Treasure!!!\r\n");
richTextBox1.AppendText("The End Of The Adventure!");
}
}
您正在重新声明变量。那是你的问题。声明变量时,可以设置类型:
string aaxe = null;
string atre = null;
当你调用一个变量时,你只需要通过变量名来调用它:
aaxe = "y";
像这样:
public partial class Form1 : Form
{
// Set the variables here
string aaxe = null;
string atre = null;
public Form1()
{
InitializeComponent();
}
public void Treasure_Click(object sender, EventArgs e)
{
if (atre == null)
{
richTextBox1.AppendText("You Haven't Found the Treasure Yet!\r\n");
// When you call a variable, you don't need to add the 'string' type.
aaxe = "y"
}
if (atre == "y")
{
richTextBox1.AppendText("You Found The Treasure!!!\r\n");
richTextBox1.AppendText("The End Of The Adventure!");
}
}
public void Axe_Click(object sender, EventArgs e)
{
// Then, when you check the value of aaxe, it will = "y".
if (aaxe == null)
{
richTextBox1.AppendText("You Don't Have An Axe\r\n");
}
if (aaxe == "y")
{
richTextBox1.AppendText("You Used your Axe\r\n");
}
}
}
你在不同的作用域中声明了两次变量 aaxe :一个是成员级别,另一个是局部变量。
请将第二个字符串aaxe改为aaxe = "y";没有字符串类型。
string aaxe = "y";
到
aaxe = "y";
