Question

我有以下代码来访问Lotus Form的字段（COM Interop），但我无法获取其dataType。（例如：Text，Number，DataTime）

        NotesSession notesSessionClass = new NotesSession();
        notesSessionClass.Initialize(pPassword);
        NotesDatabase pNotesDatabase= notesSessionClass.GetDatabase("", pDatabaseName, false);
        object objectForms = pNotesDatabase.Forms;
        Array formArray = (System.Array)objectForms;

        for (int cnt = 0; cnt < formArray.Length; cnt++)
        {
            NotesForm localForm = (NotesForm)formArray.GetValue(cnt);

            Array fieldsArray = (System.Array)localForm.Fields;
            for (int fieldCnt = 0; fieldCnt < fieldsArray.Length; fieldCnt++)
            {
                string field = (string)fieldsArray.GetValue(fieldCnt);
                FIELD_TYPE fieldType = localForm.GetFieldType(field);
                string strFieldType = fieldType.ToString();
             }
         }

Answer 1

GetFieldType返回一个整数。可能的值在NotesItem.Type的文档中进行了解释。

Answer 3

当字段是列表或多值项时，显然存在“秘密特征”，其将类型值加1。所以，如果你得到1281，那就告诉你它是一个文本列表。那是谣言！
