简单控制台应用程序中的“无法将类型'string'隐式转换为'int'”错误

Question

我在C＃密码控件中收到此错误：

  

无法将类型'string'隐式转换为'int'

请您帮忙？

int newPassPP2 = 19;

Console.WriteLine("Enter the Password : ");

int readNewPassword = int.Parse(Console.ReadLine());

int writeNewPassword(int newNumOne)
{
    return newNumOne == readNewPassword ? "Number is true" : "Number is false";
}
Console.WriteLine(writeNewPassword(newPassPP2));

此代码行上发生错误：

return newNumOne == readNewPassword ? "Number is true" : "Number is false";

谢谢

Answer 1

您需要从本地方法返回一个字符串

   ...

   string writeNewPassword(int newNumOne)
   {
      return newNumOne == readNewPassword ? "Number is true" : "Number is false";
   }
   Console.WriteLine(writeNewPassword(newPassPP2));

   ...

您的方法返回类型为 int ，现在将其更改为 string 的数据类型，

private string myMethod()
