The new( ) constructor constraint enables you to instantiate an object of a generic type Normally, you cannot create an instance of a generic type parameter However, the new( ) constraint changes this because it requires that a type argument supply a public parameterless constructor This can be the default constructor provided automatically when no explicit constructor is declared or a parameterless constructor explicitly defined by you With the new( ) constraint in place, you can invoke the parameterless constructor to create an object Here is a simple example that illustrates the use of new( ): 00014 00055 00123 00218 00341 asp.net upc-a Barcode UPC-A - CodeProject

In Figure 21-8, there is a specific column to show the Year/Year Variance With Alerters you can define a formula within the alert Thus, Revenue numbers appear in the report, but the alerter works off a variance calculation In previous versions of BusinessObjects, you had to first define a formula or variable and then apply the alerter to the new variable In Web Intelligence, you can define a formula as part of the alerter In the following example, the alerter calculates the number of days between an order s required date and ship date If the difference is less than 0, the shipment is late and the format for that row of data will be different public Test() { // This works because of the new() constraint obj = new T(); // create a T object } 6 7 8 9 10 A new object of type T is created and a reference to it is assigned to obj This statement is valid only because the new( ) constraint ensures that a constructor will be available To prove this, try removing the new( ) constraint and then attempt to recompile the program As you will see, an error will be reported In Main( ), an object of type Test is instantiated, as shown here: 21: Test<MyClass> x = new Test<MyClass>(); Notice that the type argument is MyClass, and that MyClass defines a parameterless constructor Thus, it is valid for use as a type argument for Test It must be emphasized that it was not necessary for MyClass to explicitly declare a parameterless constructor Its default constructor would also satisfy the constraint However, if a class needs other constructors in addition to a parameterless one, then it would be necessary to also explicitly declare a parameterless version, too There are three important points about using new( ) First, it can be used with other constraints, but it must be the last constraint in the list Second, new( ) allows you to construct an object using only the parameterless constructor, even when other constructors are available In other words, it is not permissible to pass arguments to the constructor of a type parameter Third, you cannot use new( ) in conjunction with a value type constraint, described next 000082 000130 000194 000275 000375
