C# method to count the number of numbers in strings

This article describes the method of counting the number of numbers in a C# string. Share it for your reference. The specific implementation method is as follows:

// 
// Used during compilation: /target:libraryusing System; 
// Declare the same namespace as the namespace in .  This allows only// Add type to the same namespace.namespace Functions 
{
 public class DigitCount 
 {
  // NumberOfDigits static method calculation  // The number of numeric characters in the passed string:  public static int NumberOfDigits(string theString) 
  {
   int count = 0; 
   for ( int i = 0; i &lt; ; i++ ) 
   {
    if ( (theString[i]) ) 
    {
     count++; 
    }
   }
   return count;
  }
 }
}

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