C#删除字符串中所有的空字符

1 string sourceStr = "Hi,   Bo ys "; 
2 char[] pChar = sourceStr.ToCharArray();//转换成字符数组
3  IEnumerator p = pChar.GetEnumerator();//得到IEnumerator 对象
4  StringBuilder sbBuilder = new StringBuilder();
5 while (p.MoveNext())//调用IEnumerator 对象的MoveNext方法
6    {
7     sbBuilder.Append((char) p.Current != ' ' ? p.Current.ToString() : String.Empty);
8    }
