expression cast as an Object data type
Converts any expression that can be interpreted as an object to Object
expression can be any data type, including
a strongly typed object, as the following code fragment illustrates:
Dim oSomeClass As New CSomeClass Dim oObj As Object oObj = CObj(oSomeClass)
The following code:
casts the string
"test" to type Object and places
it in the Object variable
The operation of the CObj function is possible because all VB.NET data types are either structures or objects.
Once a data type is converted to type Object, you can display its value by calling its ToString method, as in the following code fragment:
Dim bFlag As Boolean = True oObj = CObj(bFlag) MsgBox(oObj.ToString)
Instead of using the CObj function to convert a strongly typed object to a generic Object data type, you can also use simple assignment, as the following code fragment illustrates:
Dim oSomeClass As New CSomeClass Dim oObj As Object oObj = oSomeClass
Like most of the conversion functions, CObj is not actually a function in the Microsoft.VisualBasic namespace. Instead, it is similar to a Visual C++ macro; the compiler translates the function call into inline code.
The CObj function is new to VB.NET. The closest equivalent in VB 6 is CVar, which converts a data type ...
