When is a static variable created in Visual Basic?

Say I have a static variable in a function:

Private Sub SomeFunction()
    Static staticVar As String = _myField.Value
End Sub

When, exactly, is this value from the _myField assigned to staticVar? When you first call the function? Instant surrounding class?

A Staticvariable is created when it is assigned, obviously.

If this line is started, not earlier, but not after.

Put a breakpoint on it and you will see.

Static means that the value will be saved between calls.

The VB.NET compiler creates a static (shared in VB.NET) class variable to maintain the value of "staticVar". Thus, it is initialized, like any other static / shared variable, the first time you use the static field of this class (or when you call this method).
