Re: Deklaration in .NET

Willkommen in der realen .Net Welt, Besucher aus dem Spottlight. Aus MSDN: Due to changes made which allow Visual Basic .NET arrays and structures (formerly known as user-defined types) to be fully compatible with other Visual Studio .NET languages, fixed-length strings are no longer supported in the language. In most cases this is not a problem, because there is a compatibility class which provides fixed-length string behavior, so the code: Dim MyFixedLengthString As String * 100 upgrades to the following: Dim MyFixedLengthString As New VB6.FixedLengthString(100) However, fixed-length strings do cause a problem when used in structures. The problem arises because the fixed-length string class is not automatically created when the structure is created. Likewise, fixed-size arrays are not created when the structure is created. When your code is upgraded, user-defined types with fixed-length strings or arrays will be converted to structures and marked with a comment telling you to initialize the fixed-length string or array before referencing the structure in code. However, you can shield yourself from this modification by changing your Visual Basic 6.0 user-defined types to use strings instead of fixed-length strings, and uninitialized arrays instead of fixed-size arrays. For example: Private Type MyType MyArray(5) As Integer MyFixedString As String * 100 End Type Sub Bar() Dim MyVariable As MyType End Sub can be changed to: Private Type MyType MyArray() As Integer MyFixedString As String End Type Sub Bar() Dim MyVariable As MyType ReDim MyVariable.MyArray(5) As Integer MyVariable.MyFixedString = String$(100, " ") End Sub
