ado.net – 无法为DataTable WriteXML,因为Windows Search返回作者属性的字符串数组

DataTable xmlFriendlyTable = oldTable.Clone();
xmlFriendlyTable.columns["Author"].DataType = typeof(String);
xmlFriendlyTable.columns["Author"].columnMapping = MappingType.Element;
foreach(var row in oldTable.Rows) {
    object[] rowData = row.ItemArray;
    object[] cpyRowData = new object[rowData.Length];
    for(int i = 0; i<rowData.Length; i++) {
        if(rowData[i] != null && rowData[i].GetType() == typeof(String[])) {
            cpyRowData[i] = String.Join("; ",(rowData[i] as String[]));
        } else {
            cpyRowData[i] = rowData[i];
        }
        xmlFriendlyTable.Rows.Add(cpyRowData);
    }
}
xmlFriendlyTable.WriteXml( ... );

注意在Web浏览器中写了上述内容,因此可能存在语法错误.
