问题描述

亲爱的,

这是我的代码。

i可以创建xml文件。

但它只写最后一行值。

不写所有行。





public void drtoXML ()

{

SqlConnection Conn = new SqlConnection(Data Source =; Initial Catalog = Employee;);

string sqlText =从EMP FOR XML AUTO中选择*;

SqlCommand dataCmd = new SqlCommand(sqlText,Conn);

XmlWriter writer = null;

Conn .Open();

}



}

dataReader.C lost();

Conn.Close();



}
