C#和VB.net的语法相差还是比较大的. 可能你会C#,可能你会VB.

将它们俩放在一起对比一下你就会很快读懂,并掌握另一门语言.

相信下面这张图会对你帮助很大.

Comments

VB.NET

'Single line only



Rem Single line only

C#

// Single line



/* Multiple



line */



/// XML comments on single line



/** XML comments on multiple lines */

Data Types

VB.NET

'Value Types



Boolean



Byte



Char (example: "A")



Short, Integer, Long



Single, Double



Decimal



Date 











'Reference Types



Object



String















Dim x As Integer



System.Console.WriteLine(x.GetType())



System.Console.WriteLine(TypeName(x)) 











'Type conversion



Dim d As Single = 3.5



Dim i As Integer = CType (d, Integer)



i = CInt (d)



i = Int(d)

C#

//Value Types



bool



byte, sbyte



char (example: 'A')



short, ushort, int, uint, long, ulong



float, double



decimal



DateTime 











//Reference Types



object



string















int x;



Console.WriteLine(x.GetType())



Console.WriteLine(typeof(int)) 











//Type conversion



float d = 3.5;



int i = (int) d

Constants

VB.NET

Const MAX_AUTHORS As Integer = 25



ReadOnly MIN_RANK As Single = 5.00

C#

const int MAX_AUTHORS = 25;



readonly float MIN_RANKING = 5.00;

Enumerations

VB.NET

Enum Action



  Start



  'Stop is a reserved word



[Stop]



  Rewind



  Forward



End Enum







Enum Status



   Flunk = 50



   Pass = 70



   Excel = 90



End Enum







Dim a As Action = Action.Stop 



If a <> Action.Start Then _



'Prints "Stop is 1" 



   System.Console.WriteLine(a.ToString & " is " & a)







'Prints 70



System.Console.WriteLine(Status.Pass)



'Prints Pass



System.Console.WriteLine(Status.Pass.ToString())
