报错:找不到数据源

[MeChecksV]

我的代码是在另一台电脑写的 我把程序过来放在公司的电脑上就报找不到数据库
我测试了连接串没有问题,不知道问题出在什么地方 后台的代码如下

namespace WebApplication1
{
    public partial class test02 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            this.ListView1.AlternatingItemTemplate = new TempLate("AlternatingItemTemplate");
            this.ListView1.EmptyDataTemplate = new TempLate("EmptyDataTemplate");
            DataSet ResultSet = RunQuery("Select * From UserInfo");
            ListView1.DataSource = ResultSet;
            ListView1.DataBind();
        }

        DataSet RunQuery(String QueryString)
        {

            // Declare the connection string. This example uses Microsoft SQL Server 
            // and connects to the Northwind sample database.
            String ConnectionString = "Data Source=XU-AE42BC5C42AC;Initial Catalog=uzone;Persist Security Info=True;User ID=sa;Password=sa";

            SqlConnection DBConnection = new SqlConnection(ConnectionString);
            SqlDataAdapter DBAdapter;
            DataSet ResultsDataSet = new DataSet();

            try
            {

                // Run the query and create a DataSet.
                DBAdapter = new SqlDataAdapter(QueryString, DBConnection);
                DBAdapter.Fill(ResultsDataSet);

                // Close the database connection.
                DBConnection.Close();

            }
            catch (Exception ex)
            {

                // Close the database connection if it is still open.
                if (DBConnection.State == ConnectionState.Open)
                {
                    DBConnection.Close();
                }

               // Message.Text = "Unable to connect to the database.";

            }

            return ResultsDataSet;

        }

        public class TempLate : ITemplate
        {
            private string templateType = ""; 
            public TempLate(string type)
            {
                this.templateType = type;
            }

            //region ITemplate Members

            public void InstantiateIn(Control container)
            {
                Label UserIDLabel = new Label();
                Label UserNameLabel = new Label();
                Label GroupIDLabel = new Label();
                UserIDLabel.ID="UserIDLabel";
                UserIDLabel.Text = "<%# Eval(\"UserID\") %>";
               
                UserNameLabel.ID="UserNameLabel";
                GroupIDLabel.ID="GroupIDLabel";
                switch (this.templateType) 
                {
                    case "AlternatingItemTemplate":
                        container.Controls.Add(new LiteralControl("<tr><td>"));
                        container.Controls.Add(UserIDLabel);
                        container.Controls.Add(new LiteralControl("</td><td>"));
                        container.Controls.Add(UserNameLabel);
                        container.Controls.Add(new LiteralControl("</td><td>"));
                        container.Controls.Add(GroupIDLabel);
                        container.Controls.Add(new LiteralControl("</td></tr>"));
                        break;
                    case "EmptyDataTemplate":
                        container.Controls.Add(new LiteralControl("<tr></tr>"));
                        break;
                        


                }
                
            }

            
       


            //endregion
        } 


        
    }
}

报这样的错误:The IListSource does not contain any data sources.

连接字符串你可以改为这样

String ConnectionString ="server=.;database=你的数据库;user id=sa;password=sa;min pool size=4;max pool size=512;";

[Krismeng]

DataSet ResultSet = RunQuery("Select * From UserInfo");
ListView1.DataSource = ResultSet;
看看ResultSet是不是NULL

[MeChecksV]

我不太清楚如何设置断点进行调试排错..

[wfcfan]

close()
应该写在filly里边吧。

断点调试确定你的数据库被打开
