推荐答案

这意味着您要将值添加到变量的现有值中.因此，例如:

It means that you want to add the value to the existing value of the variable. So, for instance:

Dim x As Integer = 1
x += 2  ' x now equals 3

换句话说，就是这样做:

In other words, it would be the same as doing this:

Dim x As Integer = 1
x = x + 2  ' x now equals 3

供将来参考，您可以在 MSDN .

For future reference, you can see the complete list of VB.NET operators on the MSDN.
