Check datatype in C#.net

Hi,
i need to call a user-defined conversion function "ScientificToDecimal" when ever value retrieved is not float

some times values is like >> 2.125900000000000e+004 OR >> 2.12
so i want to convert from Scientific to Decimal if the value is not float datatype.
Note:- 'ScientificToDecimal' function works fine though

Is there a way ?

Environment:- C#net, ASP.Net 2.0

/// sample code ////
 if ((float.TryParse(drowpnl["start_qty"].ToString(), out flt)))
{
 decimal dc_start_qty =  scientificTOdecimal(drowpnl["start_qty"].ToString());
 drowpnl["start_qty"] = string.Format("{0:N2}", dc_start_qty);
}

//// ScientificTodecimal /////
 protected decimal scientificTOdecimal(string varstr)
 {
   return (decimal.Parse(varstr,    System.Globalization.NumberStyles.Float));
 }

try the following code

string x = "2.125900000000000e+004";
            double d = Double.Parse(x, System.Globalization.NumberStyles.Float)

Hi mali kirfan28,

as i mentioned, String x is not always in this format ( Ex:-"2.125900000000000e+004";)

I'm not sure what you're asking...do you mean if the string is "Hello World" you don't want to try and convert it to a decimal?

Hello tgerbert,

i am trying read values from xml file ... which are in Scientific format... and some in decimal

so i want to convert those which are in scientific format Ex:-"2.125900000000000e+004";

do i make any sense........
i 'm sorry if my basic approach is wrong... would appreciate if corrected

Todd Gerbert

So if it's NOT in scientific notation you don't want to convert it, even if it's a valid decimal value?

Give me an example of what should be converted, and what shouldn't, and why.
