ADO.NET in a Nutshell

Structures

C# uses the struct statement along with opening and closing braces to indicate the beginning and end of a structure definition. For example, System.Windows.Forms.DataGridCell is defined in C# as follows:

public struct DataGridCell {

   // member definitions

}

In VB, a structure definition is indicated by the Structure ... End Interface construct:

Public Structure DataGridCell

   ' member definitions

End Structure

C# uses the colon with structures to indicate interface implementation. Any implemented interfaces are part of the class statement. In VB, any implemented interfaces are specified by an Implements statement on the line immediately following the Structure statement. However, none of the structures documented in the reference section of this book use interface inheritance.
