分享把conn.cs做成conn.dll形式后在asp.net中如何调用??
conn.cs:
using System;
using System.Data;
using System.Data.SqlClient;
namespace connn{
public class conn
{
public DataSet returnSet()
{
string mySelectQuery = "select * from class where name=rrr";
SqlConnection myConnection = new SqlConnection("server=localhost;uid=Aro;pwd=;database=master");
SqlCommand selectCMD = new SqlCommand(mySelectQuery,myConnection);
SqlDataAdapter custDA = new SqlDataAdapter();
custDA.SelectCommand = selectCMD;
myConnection.Open();
DataSet custDS = new DataSet();
custDA.Fill(custDS, "class");
return custDS;
}
}
}
把conn.cs做成conn.dll形式后,嵌入如下的程序中,会提示DataSource没有传到数值,麻烦大家解决一下,谢谢!
<%@ Page language="c#"%>
<%@ import namespace="System.Data"%>
<%@ import namespace="System.Data.SqlClient"%>
<%@ import namespace="connn"%>
<HTML>
<HEAD>
<script language="C#" runat="server">
private void Page_Load(Object Src,EventArgs E) {
DataSet custDS = new DataSet();
MyDataGrid.DataSource=custDS;
MyDataGrid.DataBind();
}
</script>
</HEAD>
using System;
using System.Data;
using System.Data.SqlClient;
namespace connn{
public class conn
{
public DataSet returnSet()
{
string mySelectQuery = "select * from class where name=rrr";
SqlConnection myConnection = new SqlConnection("server=localhost;uid=Aro;pwd=;database=master");
SqlCommand selectCMD = new SqlCommand(mySelectQuery,myConnection);
SqlDataAdapter custDA = new SqlDataAdapter();
custDA.SelectCommand = selectCMD;

}

试试看先把一个xml文件的内容fill到dataset当中吧,会不会是数据库那头的问题啊

请按我下面的程序来做，就不会出错了，我的是beta2。
using System;
using System.Data;
using System.Data.SqlClient;
namespace connn
{
public class conn
{
public DataSet returnSet()
{
string mySelectQuery = "select * from authors";
SqlConnection myConnection = new SqlConnection("server=localhost;uid=sa;pwd=;database=pubs");
SqlDataAdapter custDA = new SqlDataAdapter(mySelectQuery,myConnection);
myConnection.Open();
DataSet custDS = new DataSet();
custDA.Fill(custDS, "class");
myConnection.Close();
return custDS;
}
}
}
在工程的Add Reference中添加一个对你的dll的引用，然后在程序里就可以使用了。
在引用它的程序的后端脚本里写Page_Load：
connn.conn a=new connn.conn();
DataGrid1.DataSource=a.returnSet();
DataGrid1.DataBind();
using System;
using System.Data;
using System.Data.SqlClient;
namespace connn
{
public class conn
{
public DataSet returnSet()
{
string mySelectQuery = "select * from authors";
SqlConnection myConnection = new SqlConnection("server=localhost;uid=sa;pwd=;database=pubs");
SqlDataAdapter custDA = new SqlDataAdapter(mySelectQuery,myConnection);
myConnection.Open();
DataSet custDS = new DataSet();
custDA.Fill(custDS, "class");
myConnection.Close();
return custDS;
}
}
