DataTable常用操作总结

【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();
