The line
线
if (userInput = mag.randomMagnifier())
should be
应该
if (userInput == mag.randomMagnifier())
回答by Ravindra Bagale
Correct this:
更正一下：
if (userInput = mag.randomMagnifier())
to:
到：
if (userInput == mag.randomMagnifier())
Here you are assigning the value in the ifstatement, which is wrong. You have to check the condition, for checking condition u have to use "==".ifstatement returns boolean values, and because you are assigning value here, it's giving the error.
这里你在if语句中赋值，这是错误的。您必须检查条件，为了检查条件，您必须使用"==". if语句返回布尔值，并且因为您在此处分配值，所以它给出了错误。
回答by AntoineLev
you should use == instead of = change:
Lif(userinput = mag.randommagnifier())for
你应该使用 == 而不是 = change:
Lif(userinput = mag.randommagnifier())for
if(userinput == mag.randommagnifier())
回答by Tejas Sharma
An if statement always contains an expression which evaluates to a boolean value. Your line
if 语句总是包含一个计算结果为布尔值的表达式。你的线路
if (userInput = mag.randomMagnifier())
is not a boolwhich is what is causing the error. You probably meant
不是bool导致错误的原因。你可能是说
if (userInput == mag.randomMagnifier())
回答by Edmond Kotowski
The condition
条件
userInput = mag.randomMagnifier()
needs to be
需要是
userInput == mag.randomMagnifier()
What you have is trying to assign the userInput value and then it tries to convert the int to bool. With C# this is not possible.
您所拥有的是尝试分配 userInput 值，然后尝试将 int 转换为 bool。使用 C# 这是不可能的。
