Exemplos

The following example creates a package, and adds a variable, myVar, to its variable collection.

static void Main(string[] args)
        {
            Package p = new Package();
            //Add a variable, myvar, to the package variables
            // collection. The variable has a value of 5, in the myNamespace
            // namespace.
            Variable var = p.Variables.Add("myVar", false, "myNamespace", 5);
            //
            // Enter the rest of your code here.
            //
        }

Shared  Sub Main(ByVal args() As String)
            Dim p As Package =  New Package() 
            'Add a variable, myvar, to the package variables
            ' collection. The variable has a value of 5, in the myNamespace
            ' namespace.
            Dim var As Variable =  p.Variables.Add("myVar",False,"myNamespace",5) 
            '
