      private static Regex RegPhone = new Regex("^[0-9]+[-]?[0-9]+[-]?[0-9]{1}$"); 
private static Regex RegNumber = new Regex("^[0-9]+{1}$"); 
private static Regex RegNumberSign = new Regex("^[+-]?[0-9]+{1}$"); 
private static Regex RegDecimal = new Regex("^[0-9]+[.]?[0-9]+{1}$"); 
private static Regex RegDecimalSign = new Regex("^[+-]?[0-9]+[.]?[0-9]+{1}$"); //等價於^[+-]?\d+[.]?\d+$ 
private static Regex RegEmail = new Regex("^[\\w-]+@[\\w-]+\\.(com|net|org|edu|mil|tv|biz|info){1}$");//w 英文字母或數字的字符串，和 [a-zA-Z0-9] 語法一樣  
private static Regex RegCHZN = new Regex("[\u4e00-\u9fa5]");//是否有中文 

 一個例子：

[csharp]
#region 中文檢測 
 
/// <summary> 
/// 檢測是否有中文字符 
/// </summary> 
/// <param name="inputData"></param> 
/// <returns></returns> 
public static bool IsHasCHZN(string inputData) 
{ 
    Match m = RegCHZN.Match(inputData); 
    return m.Success; 
}
