在 vscode 中使用 C# 输入控制台应用程序

我试图通过制作一个控制台游戏来测试我的傻瓜大脑，因为我认为我很擅长编程，并且陷入了库存（即在库存中的每个项目上进行 foreach你按“我”）但意识到我太笨了。这就是我写的：

string i;
var input = Console.ReadKey();
if (input = 'I') {
    foreach (KeyValuePair<string, string> item in Inventory)
    {
        i += $"{item.Key}: {item.Value}";
    }
}
else {
    Console.WriteLine("(Press 'I' to open your inventory.)");
}

我知道，这可能会杀死一个程序员（我很无趣）。这是错误消息：

    C:\Documents\new pogram\internet be broke 2 electric boogaloo.cs(19,13): error CS0103: The name 'I' does not exist in the current context 
    
    C:\Documents\new pogram\internet be broke 2 electric boogaloo.cs(22,9): error CS0165: Use of unassigned local variable 'i' [C:\Users\lewis_pulfff2\OneDrive\Documents\new pogram\new pogram.csproj]

The build failed. Fix the build errors and run again.

我尝试寻找其他软件，但示例不起作用。

i tried to test my dum-dum brain by making a console game because i thought that i was gud at programming, and got stuck on the inventory (i.e. going through a foreach for each item in the inventory when you press 'I') but realised i'm too dum-dum for that. here's what i wrote:

string i;
var input = Console.ReadKey();
if (input = 'I') {
    foreach (KeyValuePair<string, string> item in Inventory)
    {
        i += quot;{item.Key}: {item.Value}";
    }
}
else {
    Console.WriteLine("(Press 'I' to open your inventory.)");
}

i know, this could kill a PROgrammer (i'm so unfunny). here were the error messages:

    C:\Documents\new pogram\internet be broke 2 electric boogaloo.cs(19,13): error CS0103: The name 'I' does not exist in the current context 
    
    C:\Documents\new pogram\internet be broke 2 electric boogaloo.cs(22,9): error CS0165: Use of unassigned local variable 'i' [C:\Users\lewis_pulfff2\OneDrive\Documents\new pogram\new pogram.csproj]

The build failed. Fix the build errors and run again.

i tried looking else ware, but the samples didn't work.

arigatogozaimasu (and gomennasorry) in advance :D.

我假设您曾经

   if (input = I)

在发布代码之前更改过它 - 这是第一个错误的原因。

您还意味着

   if (input == 'I')  <<<  '==' means compare '=' means assign

EDIT

加 ReadKey 返回的内容多于按键 - 请参阅 https://learn.microsoft.com/en-us/dotnet/api/system.console.readkey?view=net-6.0

所以你需要

  if(input.Key == 'I')

第二个错误来自

 string i;   <<<<======= this doesnt create an empty string (i is null)

你需要的

string i = "";
var input = Console.ReadKey();
if (input == 'I') {
    foreach (KeyValuePair<string, string> item in Inventory)
    {
        i += $"{item.Key}: {item.Value}";
    }
}
else {
    Console.WriteLine("(Press 'I' to open your inventory.)");
}

I will assume that you used to have

   if (input = I)

but changed that before posting the code - this was the cause of the first error.

also you mean

   if (input == 'I')  <<<  '==' means compare '=' means assign

EDIT

plus ReadKey returns more than the key press - see https://learn.microsoft.com/en-us/dotnet/api/system.console.readkey?view=net-6.0

so you need

  if(input.Key == 'I')

THe second error comes from here

 string i;   <<<<======= this doesnt create an empty string (i is null)

you need

string i = "";
var input = Console.ReadKey();
if (input == 'I') {
    foreach (KeyValuePair<string, string> item in Inventory)
    {
        i += quot;{item.Key}: {item.Value}";
    }
}
else {
    Console.WriteLine("(Press 'I' to open your inventory.)");
}
