vb.net轉換ass,vb60转net
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

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字符串 替换
x="a[11dsfsf]b"
b=x.lastindexof("]")
a=x.indexof("[")
x=x.substring(0,a) "0" x.substring(b)
vb.net,强类型转换
这属于装箱拆箱。我举个例子你就明白了:
Dim x As Integer = 5
Dim o As Object = x '装箱
Dim y As Integer = CType(o, Integer) '拆箱(在Option Strict Off的情况下,直接用o给y赋值,会发生自动转换,也就是说在这种情况下,你不必显式调用CType函数)
另外:VB.NET支持后期绑定,所以你也可以不进行拆箱,直接在Object类型下就可以调用它的属性和方法
比如,下面的语句在Option Strict Off是是合法的
Dim s As String = 886
Dim i As Integer = "53"
Dim f As Object = New Form()
f.Show() '注意,f是Object类型的
总之,VB.NET的语法要比C#灵活得多
