ローカルマシンでは問題なく動作します。temp から App_Web_kvw1yfpt.2.cs を削除すると、エラーが発生し続けます。助言がありますか ？

ありがとう

Kodu.Libs.Utils.GetDRInt(..) のコード:

public static int GetDRInt(DataRow row, string name)
        {
            return row[name] != DBNull.Value ? (int)row[name] : -1;
        }

関数を次のようにします。

public static int GetDRInt(DataRow row, string name)
{
    Debug.Assert(name != null, "Name must have a value");

    if(row == null || row[name] == null || row[name] == DBNull.Value)
       return -1
    else
       return (int)row[name];
}

可能なすべての null ケースをチェックします。
