c# - C# I am having trouble with variables not acting as I would expect

Question

I am trying to emulate a dice rolling and if the die lands on a certain number then it does something, and if it lands on another number it does something else. However, I am having trouble with this. Where it says if (hitPoints = 1) I am getting the error:

Cannot implicitly convert type 'int' to 'string.'

But you can clearly see that it is indeed a string. Any help on this problem would be very much appreciated, thank you in advance.

Random r = new Random();
    int hit = r.Next(1, 5);
    string hitPoints = hit.ToString();


    EmbedBuilder builder = new EmbedBuilder();



    if (hitPoints = 1)
    { 
        builder.WithTitle("");
    }

欢迎来到堆栈溢出！

我看到您已声明并分配hitpoints为字符串：

string hitPoints = hit.ToString();

但在此之下，您正在将其（我希望）与一个数字进行比较：

if (hitPoints = 1)

那里有两个问题。首先，这不是比较运算符。其次，文字1不是字符串。

如果你真的想hitPoints成为一个字符串，并且你想将它与它进行比较，1那么试试这个：

if (hitPoints == "1")

旁注：请允许我建议您不要将其存储hitPoints为字符串，而只是将其作为一个字符串输出。您可以随时调用.ToString()现有hit变量：

int hit = r.Next(1, 5);

if (hit == 1) {
    // do a thing
}

// using newer string interpolation, implicit hit.ToString()
Console.WriteLine($"Hit was {hit}");

// using old format, implicit hit.ToString()
Console.WriteLine("Hit was {0}", hit);

// using old format, explicit hit.ToString()
Console.WriteLine("Hit was {0}", hit.ToString());
