Application experience of vb.net generic type

Vb. NET programming language has a wide variety of data types, it is a difficult step for beginners to master all these types of applications. Today, let's get to know the application of the higher-order technology of the vb.net generic type, so that we can understand the language in depth.

When you define a vb.net generic type, it is parameterized even with one or more data types. This allows you to customize the data type with code to meet its requirements. The code can declare several different programming elements through a generic element, each of which can use a different set of data types. However, regardless of which data types are used by the declared element, they perform the same logic.

Base class definition

Namespace result public    MustInherit Class result public        Sub New ()        End Sub Property        msg as String        Property success as Boolean    End classend Namespace

　　

To define a function implementation:

    Shared Function Resultt (Of T as Models.result.result) (msg as String) as T        Dim rsp As T = Nothing        Dim parser as Mod Els.result.result = Nothing        rsp.msg = msg        rsp.success = False        return RSP        ' return New API. Resultobj (of T) with {. msg = msg,. Success = False}    End Function

　　

Invocation Example:

Return RESULTT (of Models.result.httputil) (msg)
