关键代码：
/// <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>publicstaticintParseThousandthString(thisstringthousandthStr)
{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;
}
单元测试：
[TestMethod()]publicvoidParseThousandthStringTest()
{string_thousandthStr ="-111,222,333";int_expected1 = -111222333;int_actual1 = StringToolV2.ParseThousandthString(_thousandthStr);
Assert.AreEqual(_expected1, _actual1);
}
希望有所帮助！
