一.从DataTable写入Xml
private void button1_Click(object sender, System.EventArgs e)
{
DataTable dtTCCL0001 = QueryTCCL0001();
string strFile = "D:\\TCCL0001.xml";
XmlTextWriter objXml = new XmlTextWriter(strFile,Encoding.UTF8);
objXml.WriteStartDocument();
objXml.WriteStartElement("InventoryXML");
objXml.WriteElementString("TransferID","123");
for(int i=0;i<dtTCCL0001.Rows.Count;i++)
{
objXml.WriteStartElement("Inventory");
objXml.WriteElementString("WareHouseNo",dtTCCL0001.Rows[i]["WareHouseNo"].ToString());
objXml.WriteElementString("CustomerCode",dtTCCL0001.Rows[i]["CustomerCode"].ToString());
objXml.WriteElementString("CustomerPartNo",dtTCCL0001.Rows[i]["CustomerPartNo"].ToString());
objXml.WriteElementString("CustomerPartNoVersion",dtTCCL0001.Rows[i]["CustomerPartNoVersion"].ToString());
objXml.WriteElementString("VendorCode",dtTCCL0001.Rows[i]["VendorCode"].ToString());
objXml.WriteElementString("VendorName",dtTCCL0001.Rows[i]["VendorName"].ToString());
objXml.WriteElementString("VendorPartNo",dtTCCL0001.Rows[i]["VendorPartNo"].ToString());
objXml.WriteElementString("VendorPartNoVersion",dtTCCL0001.Rows[i]["VendorPartNoVersion"].ToString());
objXml.WriteElementString("MFGCode",dtTCCL0001.Rows[i]["MFGCode"].ToString());
objXml.WriteElementString("InventoryQty",dtTCCL0001.Rows[i]["InventoryQty"].ToString());
objXml.WriteElementString("PartStatus",dtTCCL0001.Rows[i]["PartStatus"].ToString());
objXml.WriteElementString("OnWayQty",dtTCCL0001.Rows[i]["OnWayQty"].ToString());
objXml.WriteElementString("UOM",dtTCCL0001.Rows[i]["UOM"].ToString());
objXml.WriteElementString("Description",dtTCCL0001.Rows[i]["Description"].ToString());
objXml.WriteElementString("Ref1",dtTCCL0001.Rows[i]["Ref1"].ToString());
objXml.WriteElementString("Ref2",dtTCCL0001.Rows[i]["Ref2"].ToString());
objXml.WriteElementString("Ref3",dtTCCL0001.Rows[i]["Ref3"].ToString());
objXml.WriteElementString("Ref4",dtTCCL0001.Rows[i]["Ref4"].ToString());
objXml.WriteEndElement();
}
objXml.WriteEndElement();
objXml.WriteEndDocument();
objXml.Flush();
objXml.Close();
txtMessage2.Text = "转换成功";
}
二.从Xml返回到DataTable
private void Button1_Click(object sender, System.EventArgs e)
{
XmlTextReader xtr = new XmlTextReader(@"D:\\TCCL0001.xml");
while(xtr.Read())
{
if(xtr.NodeType == XmlNodeType.Element)
{
switch(xtr.LocalName)
{
case "TransferID":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "WareHouseNo":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "CustomerCode":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "CustomerPartNo":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "CustomerPartNoVersion":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "VendorCode":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "VendorName":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "VendorPartNo":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "VendorPartNoVersion":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "MFGCode":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "InventoryQty":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "PartStatus":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "OnWayQty":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "UOM":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "Description":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "Ref1":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "Ref2":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "Ref3":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
case "Ref4":
HttpContext.Current.Response.Write(xtr.ReadString()+ "<br>");
break;
}
}
}
}
