XMLWriter条件 [英] XMLWriter conditions

问题描述

我有一个用于打印标签的表格.它是2列标签x 5行.这基于Infopath.加载Infopath表单后，它将创建Windows表单，并用数据填充datagrid.然后，用户可以选择需要打印的记录.但是，我需要将行计数为奇数的每条记录都放在左侧，而行计数为偶数的每条记录都放在右边.我在左侧和右侧之间有不同的XML字段.请参见下面的代码.

I have a form that will be used to print labels. It's 2 columns of labels x 5 rows. This is based on Infopath. When the Infopath form loads, it creates a Windows Form and fills a datagrid with data. The user can then select which records need to be printed. However, I need to put every record where the row count is odd onto the left side, and every record where the row count is even on the right. I have distinct XML fields between the left and right sides. See code below.

            foreach (DataRow dr in ds.Tables["Inspection"].Rows)

            {

                strPrint = dr["Print"].ToString();

                strPN = dr["PN"].ToString();

                strOC = dr["OC"].ToString();

                strNF = dr["NF"].ToString();

                strCEMB = dr["CEMB"].ToString();

                strQty = dr["QTY"].ToString();

                strDate = dr["NF_DATE"].ToString();



                int count = ds.Tables["Inspection"].Rows.Count;



                using (XmlWriter writer = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:Section", NamespaceManager).AppendChild())

                {

                    while (i <= count)

                    {

                        if (i % 2 != 0)

                        {

                            writer.WriteStartElement("rptSection", myNameSpace);

                            writer.WriteElementString("lPN", myNameSpace, strPN);

                            writer.WriteElementString("lOC", myNameSpace, strOC);

                            writer.WriteElementString("lNF", myNameSpace, strNF);

                            writer.WriteElementString("lQty", myNameSpace, strQty);

                            writer.WriteElementString("lDate", myNameSpace, strDate);

                        }

                        else

                        {

                            writer.WriteElementString("rPN", myNameSpace, strPN);

                            writer.WriteElementString("rOC", myNameSpace, strOC);

                            writer.WriteElementString("rNF", myNameSpace, strNF);

                            writer.WriteElementString("rQty", myNameSpace, strQty);

                            writer.WriteElementString("rDate", myNameSpace, strDate);

                            writer.WriteEndElement();

                        }

                    }

                    writer.Close();

                }
}

i += 1;

}

推荐答案

只需看一眼，就好像您在一个if块中编写StartElement，在另一个if中编写EndElement一样.

希望这会有所帮助.

Just glancing at this, it looks like you are writing the StartElement in one if block and the EndElement in the else. Depending on your count, it would seem possible to have one without the other, causing the error.

Hope this helps.
