string strTemp = "0.51667308807373";

convert to decimal by rounding of two decimal places.

Answer 1

Math.Round(Convert.ToDecimal(strTemp), 2);

Answer 2

First convert string to decimal (Using Decimal.Parse or Decimal.TryParse).

decimal d = Decimal.Parse("123.45678");

Then round the decimal value using Round(d, m) where d is your number, m is the number of decimals, see http://msdn.microsoft.com/en-us/library/6be1edhb.aspx

decimal rounded = Decimal.Round(d, 2); 

If you only want to round for presentation, you can skip rounding to a decimal and instead simply round the value in output:

string.Format("{0:0.00}", 123.45678m);
