推荐答案

那么你可以使用正则表达式来去除，这不是资本AZ一切：

Well you could use a regular expression to remove everything that wasn't capital A-Z:

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main( string[] args )
    {
        string input = "Blue Cross Blue Shield 12356";
        Regex regex = new Regex("[^A-Z]");
        string output = regex.Replace(input, "");
        Console.WriteLine(output);
    }
}

请注意，这将也删除任何非ASCII字符。另一种正则表达式是：

Note that this would also remove any non-ASCII characters. An alternative regex would be:

Regex regex = new Regex(@"[^\p{Lu}]");

...我认为，应涵盖所有文化的大写字母。

... I believe that should cover upper-case letters of all cultures.
