VB.NET:在 IF 条件中为变量赋值? [英] VB.NET: Assign value to variable inside an IF condition?

问题描述

是否有可能在 VB.NET 中为 IF 条件内的变量赋值?

is there any possibility to assign a value to a variable inside an IF condition in VB.NET?

类似的东西:

Dim customer As Customer = Nothing

If IsNothing(customer = GetCustomer(id)) Then
    Return False
End If

谢谢

推荐答案

抱歉，没有.另一方面，它会变得非常混乱，因为 VB.NET 使用相同的运算符进行赋值和相等.

Sorry, no. On the other hand, it would get really confusing, since VB.NET uses the same operator for both assignment and equality.

If a = b Then 'wait, is this an assignment or comparison?!

相反，只需设置变量并进行比较:

Instead, just set the variable and compare:

Dim customer As Customer = Nothing

customer = GetCustomer(id)

If IsNothing(customer) Then
    Return False
End If
