How to get text and a variable in a messagebox

Question

I just need to know how to have plain text and a variable in a messagebox.

For example:

I can do this: MsgBox(variable)

And I can do this: MsgBox("Variable = ")

But I can't do this: MsgBox("Variable = " + variable)

Answer 1

As has been suggested, using the string.format method is nice and simple and very readable.

In vb.net the " + " is used for addition and the " & " is used for string concatenation.

In your example:

MsgBox("Variable = " + variable)

becomes:

MsgBox("Variable = " & variable)

I may have been a bit quick answering this as it appears these operators can both be used for concatenation, but recommended use is the "&", source http://msdn.microsoft.com/en-us/library/te2585xw(v=VS.100).aspx

maybe call

variable.ToString()

update:

Use string interpolation (vs2015 onwards I believe):

MsgBox($"Variable = {variable}")
