VB.NET中怎么将16进制数换成对应的ASCII，比如说&H1000，怎么把他换成31H,30H,30H,30H

Public Function dec_to_hex(dec As Long) As String

Dim a As String

dec_to_hex = ""

Do While dec 0

a = CStr(dec Mod 16)

Select Case a

Case "0": a = "30H"

Case "1": a = "31H"

Case "2": a = "32H"

Case "3": a = "33H"

Case "4": a = "34H"

Case "5": a = "35H"

Case "6": a = "36H"

Case "7": a = "37H"

Case "8": a = "38H"

Case "9": a = "30H"

Case "10": a = "65H"

Case "11": a = "66H"

Case "12": a = "67H"

Case "13": a = "68H"

Case "14": a = "69H"

Case "15": a = "70H"

End Select

dec_to_hex = a " " dec_to_hex

dec = dec \ 16

Loop

End Function

vb.net和asp.net的区别

两者都可以开发WEB应用程序，但VB.NET是是采用VB作为开发语言，而ASP.NET是采用C#作为开发语言。而C#是微软为.NET框架专门设计的开发语言，所以更适合做.NET开发。
