關(guān)鍵代碼：

        /// <summary>        /// 將千分位字符串轉(zhuǎn)換成數(shù)字        /// 說(shuō)明：將諸如"–111,222,333的千分位"轉(zhuǎn)換成-111222333數(shù)字        /// 若轉(zhuǎn)換失敗則返回-1        /// </summary>        /// <param name="thousandthStr">需要轉(zhuǎn)換的千分位</param>        /// <returns>數(shù)字</returns>        public static int ParseThousandthString(this string thousandthStr)        {            int _value = -1;            if (!string.IsNullOrEmpty(thousandthStr))            {                try                {                    _value = int.Parse(thousandthStr, NumberStyles.AllowThousands | NumberStyles.AllowDecimalPoint | NumberStyles.AllowLeadingSign);                }                catch (Exception ex)                {                    _value = -1;                    Debug.WriteLine(string.Format("將千分位字符串{0}轉(zhuǎn)換成數(shù)字異常，原因:{0}", thousandthStr, ex.Message));                }            }            return _value;        }

單元測(cè)試：

        [TestMethod()]        public void ParseThousandthStringTest()        {            string _thousandthStr = "-111,222,333";            int _expected1 = -111222333;            int _actual1 = StringToolV2.ParseThousandthString(_thousandthStr);            Assert.AreEqual(_expected1, _actual1);        }

希望有所幫助！
