initialize and assign value to multiple variables vb.net
提问by cMinor
there is the option to do this in vb.net
可以选择在 vb.net 中执行此操作
Dim a, b, c As Single, x, y As Double, i As Integer
also you can do
你也可以做
Dim myString = String.empty
Is there a way to initialize and assign multiple variables like the first example but using the assignment as the second one?
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？

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
我在 VS 2008 中对其进行了测试，但我认为 Dim 语句的语法从那以后没有改变。如果初始化它们，则必须为每个变量指定类型
Dim a As Single = 1, b As Single = 2, x As Double = 5.5, y As Double = 7.5
Or you can let VB infer the type and use type characters (here !for Single):
或者您可以让 VB 推断类型并使用类型字符（此处!为Single）：
Dim a = 1!, b = 2!, c = 3!, x = 5.5, y = 7.5, i = 100
By hovering with the cursor over the variables in VS you will see that the types are inferred correctly as Single, Doubleand Integer.
You could also use Ffor single. See: Constant and Literal Data Types (Visual Basic)
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F用于单身。请参阅：常量和文字数据类型 (Visual Basic)

我刚刚在一行中检查了此代码的多个控件声明。编译成功，窗口出现。这是一个非常大的项目的一部分。** Dim DllNumber As New TextBox,DllMethod As New TextBox,LoopBox As New TextBox** kvinvisibleguy
