数字进制转换(二进制、八进制、十进制、十六进制)

 

1.十六进制字符串转十进制数字                                             

      Dim 十进制数字 As Integer = Convert.ToInt32(十六进制字符串, 16)    

        eg. Dim i As Integer = Convert.ToInt32("bb", 16)               　　

2.十进制数字转十六进制字符串                                             

      Dim 十六进制字符串 As String = Convert.ToString(十进制数字, 16) 　 

        eg. Dim s As String = Convert.ToString(187, 16) 

3.八进制字符串转十进制数字                                            　　

      Dim 十进制数字 As Integer = Convert.ToInt32(八进制字符串, 8)　　　　

        eg. Dim i As Integer = Convert.ToInt32("15", 8)                　　

4.十进制数字转八进制字符串                                            　

      Dim八进制字符串 As String = Convert.ToString(十进制数字, 8)　　　　

        eg. Dim s As String = Convert.ToString(13, 8)  

5.二进制字符串转十进制数字                                               

      Dim 十进制数字 As Integer = Convert.ToInt32(二进制字符串, 2)       

        eg. Dim i As Integer = Convert.ToInt32("1101", 2)                 

6.十进制数字转二进制字符串                                               

      Dim二进制字符串 As String = Convert.ToString(十进制数字, 2)       

        eg. Dim s As String = Convert.ToString(13, 2)
