InlineAssignHelper

It's a helper function which you sometimes see used in the MSDN documentation and is defined like this:

Private Shared Function InlineAssignHelper(Of T)(ByRef target As T, value As T) As T

target = value

Return value

End Function

As you'll see, it assigns 'value' to the variable passed in by reference and also returns 'value'.

So, something like this in VB:

Dim sr As new StreamReader(filePath)

Dim line As String

While InlineAssignHelper(line, sr.ReadLine()) IsNot Nothing

' do something with line

End While

is equivalent to this in C#

var sr = new StreamReader(filePath);

string line;

while ((line = sr.ReadLine()) != null)

{

// do something with line

}
