C#实现将千分位字符串转换成数字的方法

/// <summary>/// 将千分位字符串转换成数字/// 说明：将诸如"111,222,333的千分位"转换成-111222333数字/// 若转换失败则返回-1/// </summary>/// <param name="thousandthStr">需要转换的千分位</param>/// <returns>数字</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("将千分位字符串{0}转换成数字异常，原因:{0}", thousandthStr, ex.Message)); }  }  return _value;}

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