示例
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)
'
' Enter the rest of your code here.
