c# - Convert currency string to decimal?

Question

Objective

Sort a string that is displaying currency data like this $1,995.94 numerically in a set of data.

Code

I'm currently using the below code sample to convert the string value to decimal so that I can sort it properly.

if (sortBy == "checkAmount")
{
    StringBuilder sb = new StringBuilder();
    foreach (var c in Convert.ToString(p.GetType().GetProperty(sortBy).GetValue(p, null)))
    {
        if (!char.IsDigit(c) && c != '.') { continue; }
        sb.Append(c);
    }
    return Convert.ToDecimal(sb.ToString());
}
else
{
    return p.GetType().GetProperty(sortBy).GetValue(p, null);
}

Problem

What's a better way of doing this? It works, and that's cool, but it's not very elegant.

Final Solution

The answer provided by Servy works as expected, and I used that implementation for a while, but a colleague and I found an even better way so I'm documenting it here. BTW, I ended up using this solution in the end.

decimal.Parse(input, NumberStyles.AllowCurrencySymbol | NumberStyles.Number);

Answer 1

How about this, but only works for one string value. So you need to get your string split by $ and then do the conversion while saving into the array or list

 using System.Globalization;
    //rest of your code

          string str = "$50,550.20";
          decimal decval;
          bool convt = decimal.TryParse(str, NumberStyles.Currency,
            CultureInfo.CurrentCulture.NumberFormat, out decval);
          if (convt) 
          Console.WriteLine(decval);
          Console.ReadLine();
