System.OverflowException：对于iis 6中的Int16，值太大或太小 [英] System.OverflowException: Value was either too large or too small for an Int16 in iis 6

问题描述

我在visual studio 2012中有一个登录方法。登录的代码是：

i have a login method writen in visual studio 2012. The code of the login is:

public DataSet Login(string UserName, string Password)
{
    DataSet Message = new DataSet();
    Tbl_Users User = new Tbl_Users();
    string ClientIP = Context.Request.ServerVariables["REMOTE_ADDR"];
    DataSet result = User.Login(UserName, Password, ClientIP);
    if (Int16.Parse(result.Tables[0].Rows[0][0].ToString()) < 0)
    {
        DataTable dt = Message.Tables.Add("results");
        dt.Columns.Add("status");
        dt.Columns.Add("results");
        DataRow row = dt.NewRow();
        row[0] = "-1";
        row[1] = ErrorFinder.SQlErrorHandeling(Int32.Parse(result.Tables[0].Rows[0][0].ToString()));
        dt.Rows.Add(row);
    }
    else
        Message = result;
    return Message;
}

当我在visual studio中执行它时，一切都还可以。但是当我通过visual studio发布网站并将其放入windows seven iis时，我收到了这个错误：

when i execute it in the visual studio, every thing is ok. but when i publish the website by visual studio and put it in the windows seven iis, i got this error:

System.OverflowException: Value was either too large or too small for an Int16.
at System.Int16.Parse(String s, NumberStyles style, NumberFormatInfo info)
at Service.Login(String UserName, String Password)

我不知道发布的网站有什么问题？

i dont know what is wrong with the published website?

推荐答案

我怀疑 result.Tables [0] .Rows [0] [0] .ToString（）包含Int16可以容纳的更大的值。所有类型的整数具有不同的以下存储容量范围

I suspect that result.Tables[0].Rows[0][0].ToString() contains larger value which a Int16 can holds. All the type of integer has different range of following storage capacity

Int 16 -- (-32768 to +32787)

Int 32 -- (-2,147,483684 to +2,147,483683)

Int 64 -- (-9223372036854775808 to +9223372036854775807)
