这些是格式化数值的示例。

Dim value As Double

value = 123
Console.WriteLine(value.ToString("00000"))
Console.WriteLine(String.Format("{0:00000}", value))
' Displays 00123

 value = 1.2
 Console.Writeline(value.ToString("0.00", CultureInfo.InvariantCulture))
 Console.Writeline(String.Format(CultureInfo.InvariantCulture, 
              "{0:0.00}", value))
' Displays 1.20

Console.WriteLine(value.ToString("00.00", CultureInfo.InvariantCulture))
Console.WriteLine(String.Format(CultureInfo.InvariantCulture, 
                            "{0:00.00}", value))
' Displays 01.20 

Dim daDK As CultureInfo = CultureInfo.CreateSpecificCulture("da-DK")
Console.WriteLine(value.ToString("00.00", daDK))
Console.WriteLine(String.Format(daDK, "{0:00.00}", value))
' Displays 01,20

value = .56
Console.WriteLine(value.ToString("0.0", CultureInfo.InvariantCulture))
Console.WriteLine(String.Format(CultureInfo.InvariantCulture, 
                            "{0:0.0}", value))
' Displays 0.6

value = 1234567890
Console.WriteLine(value.ToString("0,0", CultureInfo.InvariantCulture))  
Console.WriteLine(String.Format(CultureInfo.InvariantCulture, 
                            "{0:0,0}", value))  
' Displays 1,234,567,890       
Dim elGR As CultureInfo = CultureInfo.CreateSpecificCulture("el-GR")
Console.WriteLine(value.ToString("0,0", elGR))
Console.WriteLine(String.Format(elGR, "{0:0,0}", value))    
' Displays 1.234.567.890

value = 1234567890.123456
Console.WriteLine(value.ToString("0,0.0", CultureInfo.InvariantCulture))    
Console.WriteLine(String.Format(CultureInfo.InvariantCulture, 
                            "{0:0,0.0}", value))    
' Displays 1,234,567,890.1  

value = 1234.567890
Console.WriteLine(value.ToString("0,0.00", CultureInfo.InvariantCulture))   
Console.WriteLine(String.Format(CultureInfo.InvariantCulture, 
                            "{0:0,0.00}", value))   
' Displays 1,234.57
