what is the difference between the following syntax
1. var dtm = new DataTableManager();
2. DataTableManager dtm1 = new DataTableManager();
Many thanks,

There is absolutely no difference if used within a method. You cannot use var as a class scoped variable through. Also var can be used to handle anonymous types, which is not possible otherwise.

What is the VB.NET equivalent of the C# ? operator? [duplicate]

What is the VB.NET equivalent of the C# ? operator?
For example, how would the following code be written in VB.NET?
hp.pt = iniFile.GetValue("System", "PT").ToUpper().Equals("H") ? PT.PA : PT.SP

Historically, IIf was commonly used for that - but that does not use short-circuiting so is not quite the same. However, there is now a 3-part If:
hp.pt = If(iniFile.GetValue("System", "PT").ToUpper().Equals("H"), PT.PA, PT.SP)
that does use short-circuiting, and thus is identical to the conditional operator in C#.

You can use the If operator
hp.pt = If(iniFile.GetValue("System", "PT").ToUpper().Equals("H"), PT.PA, PT.SP)

Try using the If function like so:
x = If(condition, trueValue, falseValue)

This question is a duplicate of a question that has already been asked and answered:
Is there a conditional ternary operator in VB.NET?
here:
Dim foo as String = If(bar = buz, cat, dog)
