public partial class ADOTEST : System.Web.UI.Page {
     SqlDataAdapter da = null;
     SqlConnection cn = null;
     DataSet ds = null;

     protected void Page_Load(object sender, EventArgs e)
     {
         cn = new SqlConnection("Data Source=(local); Database=TestDb ; Uid=sa ; password=123 ");

         if (!Page.IsPostBack)
         {
             BindEmpData();  
         }
     }

     void BindEmpData()
     {
         da = new SqlDataAdapter("Select *From EMPLOYEE", cn);
         ds = new DataSet();
         da.Fill(ds, "EMPLOYEE");

         Repeater1.DataSource = ds.Tables["EMPLOYEE"];
         // Repeater1.DataSource = ds;
         // Repeater1.DataMember = "EMPLOYEE";
         Repeater1.DataBind();
     }

Answer 1

我认为连接字符串是错误的，而“选择”也是错误的

"*From"

"* From"

为了您将来的参考，以下可能是一个更好的主意：

public partial class ADOTEST : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            BindEmpData();  
        }
    }

    void BindEmpData()
    {
        using (SqlConnection cn = new SqlConnection("Data Source=(local); Database=TestDb ; Uid=sa ; password=123 "))
        {
            using (SqlDataAdapter da = new SqlDataAdapter("Select *From EMPLOYEE", cn))
            {
                DataSet ds = new DataSet();
                da.Fill(ds, "EMPLOYEE");
            }
        }
        Repeater1.DataSource = ds.Tables["EMPLOYEE"];
        Repeater1.DataBind();
    }
}

using块将确保清除资源，即使发生异常也是如此。

这段代码没有显示输出的错误是什么？我想使用转发器显示数据
