初始化并赋值给多个变量 vb.net [英] initialize and assign value to multiple variables vb.net

问题描述

可以在 vb.net 中执行此操作

there is the option to do this in vb.net

Dim a, b, c As Single, x, y As Double, i As Integer

你也可以

Dim myString = String.empty

有没有办法像第一个例子一样初始化和分配多个变量，但使用分配作为第二个例子?

Is there a way to initialize and assign multiple variables like the first example but using the assignment as the second one?

推荐答案

我在 VS 2008 中对其进行了测试，但我认为 Dim 语句的语法自那以后没有改变.如果初始化它们，则必须为每个变量指定类型

I tested it in VS 2008, but I don't think that the Syntax of the Dim statement changed since. You will have to specify the type for each variable, if you initialize them

Dim a As Single = 1, b As Single = 2, x As Double = 5.5, y As Double = 7.5

或者你可以让VB推断类型并使用类型字符(这里!为Single):

Or you can let VB infer the type and use type characters (here ! for Single):

Dim a = 1!, b = 2!, c = 3!, x = 5.5, y = 7.5, i = 100

通过将光标悬停在 VS 中的变量上，您将看到类型被正确推断为 Single、Double 和 Integer.您也可以将 F 用于单曲.请参阅:常量和文字数据类型 (Visual Basic)

By hovering with the cursor over the variables in VS you will see that the types are inferred correctly as Single, Double and Integer. You could also use F for single. See: Constant and Literal Data Types (Visual Basic)
