C# method to implement percentage to decimal

This article describes the method of C# to convert percentage to decimals. Share it for your reference. The specific analysis is as follows:

Recently, the percentage to decimal function is needed, and the percentage is in string format (can be with or without a percent sign).

If it is a decimal turn percentage, it is simple. There is a p in the number format string in C#.

But I really don’t know if the percentage is converted into decimal? I took a brief look at MSDN and didn't find it (dreaming?).

Therefore, a method is directly implemented:

/// &lt;summary&gt;
/// Convert percentages to decimals/// &lt;/summary&gt;
/// <param name="perc">Percent value, which can be purely a numeric value, or all with a % sign,/// For example: 65|65%</param>/// &lt;returns&gt;&lt;/returns&gt;
public static decimal PerctangleToDecimal(string perc)
{
  try
  {
 string patt = @"/^(?&lt;num&gt;[\d]{1,})(%?)$/";
 decimal percNum = ((perc, patt).Groups["num"].Value);
 return percNum / (decimal)100;
  }
  catch
  {
 return 1;
  }
}

The function has been implemented, but it feels a bit of a sideways.

Looking forward to the interested experts' advice~~

I hope this article will be helpful to everyone's C# programming.
