C#常用的字符串扩展方法汇总

本文实例汇总了C#常用的字符串扩展方法，分享给大家供大家参考。具体如下：

EString.cs文件如下：

/// 扩展字符串类
/// </summary>
public static class EString
{
        #region 数据转换

        #region 转Int
        /// <summary>
        /// 转Int,失败返回0

        /// <returns></returns>
        public static int ToInt(this string t)
        {
            int n;
            if (!int.TryParse(t, out n))
                return 0;
            return n;
        }

        /// <summary>
        /// 转Int,失败返回pReturn
        /// </summary>
        /// <param name="e"></param>
        /// <param name="pReturn">失败返回的值</param>
        /// <returns></returns>
        public static int ToInt(this string t, int pReturn)
        {
            int n;
            if (!int.TryParse(t, out n))
                return pReturn;
            return n;
        }

        /// <summary>
        /// 是否是Int true:是 false:否
        /// </summary>
        /// <param name="t"></param>
        /// <returns></returns>
        public static bool IsInt(this string t)
        {
            int n;
            return int.TryParse(t, out n);
        }
        #endregion

        {
            Int16 n;
            return Int16.TryParse(t, out n);
        }
        #endregion

        #region 转byte
        /// <summary>
        /// 转byte,失败返回0
        /// </summary>
        /// <param name="e"></param>
        /// <returns></returns>
        public static byte Tobyte(this string t)
        {
