示例1:

Dim style As NumberStyles
Dim culture As CultureInfo
Dim value As String
Dim number As Byte

' Parse number with decimals.
' NumberStyles.Float includes NumberStyles.AllowDecimalPoint.
style = NumberStyles.Float       
culture = CultureInfo.CreateSpecificCulture("fr-FR")
value = "12,000"

number = Byte.Parse(value, style, culture)
Console.WriteLine("Converted '{0}' to {1}.", value, number)

culture = CultureInfo.CreateSpecificCulture("en-GB")
Try
   number = Byte.Parse(value, style, culture)
   Console.WriteLine("Converted '{0}' to {1}.", value, number)
Catch e As FormatException
   Console.WriteLine("Unable to parse '{0}'.", value)   
End Try      

value = "12.000"
number = Byte.Parse(value, style, culture)
Console.WriteLine("Converted '{0}' to {1}.", value, number)
开发者ID:VB.NET开发者,项目名称:System,代码行数:25,代码来源:Byte.Parse

输出:

Converted '12,000' to 12.
Unable to parse '12,000'.
Converted '12.000' to 12.


示例2:

Dim value As String
Dim style As NumberStyles
Dim number As Byte

' Parse value with no styles allowed.
style = NumberStyles.None
value = " 241 "
Try
   number = Byte.Parse(value, style)
   Console.WriteLine("Converted '{0}' to {1}.", value, number)
Catch e As FormatException
   Console.WriteLine("Unable to parse '{0}'.", value)   
End Try
  
' Parse value with trailing sign.
style = NumberStyles.Integer Or NumberStyles.AllowTrailingSign
value = " 163+"
number = Byte.Parse(value, style)
Console.WriteLine("Converted '{0}' to {1}.", value, number)

' Parse value with leading sign.
value = "   +253  "
number = Byte.Parse(value, style)
Console.WriteLine("Converted '{0}' to {1}.", value, number)
' This example displays the following output to the console:
'       Unable to parse ' 241 '.
'       Converted ' 163+' to 163.
'       Converted '   +253  ' to 253.
