Wrong result from IsNumeric() in VB.NET

Question

I have a function in VB.NET that loops through values and attempts to convert it to a decimal if IsNumeric is True,

Dim Value As String

If IsNumeri         


        

Answer 1

See http://support.microsoft.com/kb/329488

IsNumeric returns true if it can be converted to a double which is true for 603E43 The value is however larger than what a decimal can hold

You could use the Decimal.TryParse funcion as a working alternative. See http://msdn.microsoft.com/en-us/library/9zbda557.aspx
