DataTable常用操作总结_AX

【引言】项目中经常使用DataTable,发现有好多东西,需要整理下.

protected void Page_Load(object sender, EventArgs e)

dtInfo.Columns.Contains("AX");

【追加】DataTable与XML的转换

protected void Page_Load(object sender, EventArgs e)

public string ConvertBetweenDataTableAndXML_AX(DataTable dtNeedCoveret)

public DataTable ConvertBetweenDataTableAndXML_AX(string xml)

{

System.IO.TextReader trDataTable = new System.IO.StringReader(xml.Substring(0, xml.IndexOf("<?xml")));

System.IO.TextReader trSchema = new System.IO.StringReader(xml.Substring(xml.IndexOf("<?xml")));

DataTable dtReturn = new DataTable();

dtReturn.ReadXmlSchema(trSchema);

dtReturn.ReadXml(trDataTable);

return dtReturn;

}
【追加】排序的好方法

dt.DefaultView.Sort = "ID ,Name ASC";

dt=dt.DefaultView.ToTable();
