问题描述

if (string.IsNullOrEmpty(profileList[i].CurrencyID))
          { boatProfile.CurrencyID = 0; }
          else
 { boatProfile.CurrencyID=int.Parse((profileList[i].CurrencyID)); }



crrencyID被声明为aspublic int? currencyID ..value in(profileList [i] .CurrencyID =Dkk

在else部分,它显示错误..int.Parse((profileList [i] .CurrencyID))扔了一个sysytem.formatException


crrencyID is declared aspublic int? currencyID ..value in (profileList[i].CurrencyID="Dkk"
In the else part it is showing the error..""int.Parse((profileList[i].CurrencyID)) threw a sysytem.formatException""

推荐答案

else
        {
            boatProfile.CurrencyID = 0;
            int.TryParse(profileList[i].CurrencyID, out boatProfile.CurrencyID);
        }


int j;
bool result = Int32.TryParse("-105", out j);
if (true == result)
    Console.WriteLine(j);
else
    Console.WriteLine("String could not be parsed.");

This may help.


boatProfile.CurrencyID=Convert.ToInt16((profileList[i].CurrencyID));





您尝试将数字字符串转换为数字数据类型,代码显示示例。





You attempt to cast a numeric string to a numeric data type, following code shows example.

string strInput = "10";
int intResult = 0;
try {
    intResult = Convert.ToInt16(strInput);
}
catch (Exception ex) {
    MessageBox.Show(("Error: " + ex.Message));
}







希望有帮助......
