same signature, you must fully qualify the name by adding

the name of the module, just as if you were invoking a

Shared method from the class.

If you are writing a class in C# to be used in VB.NET and

want to make it look like a module, you can simply mark

every member in the class as static, then reference the

Microsoft.VisualBasic.DLL assembly and add the

StandardModule attribute (from the Microsoft.VisualBasic.

CompilerServices namespace) to your class, as follows:

[Microsoft.VisualBasic.CompilerServices.StandardModule]

public class Math

{

public static int Add(int num1, int num2)

{

return num1+num2;

}

}

A VB project can then refer to the Add function directly with-

out the class name.

If Statements

Both languages have conditional if statements. However, the

syntax and semantics differ between the languages. In C#,

the conditional statement must be enclosed in parentheses,

as follows:

if (x > 10)

DoSomething( );

Notice that if is in lowercase, there are parentheses sur-

rounding the conditional statement, and that unlike in VB,

there is no need for

Then at the end. This example shows an

if statement with only one task to perform. If there are mul-

tiple tasks to perform, they are enclosed in curly brackets, as

follows:

if (x < 10)

{

DoTask1( );
