.net - mscorlib.dll 中出现类型为 System.StackOverflowException 的未处理异常

Question

我在 ASP.NET 中编写了一段代码，该代码从 SQL 表中读取数据并在 GridView 中显示它并使用行数据绑定(bind)事件。但是当我运行该程序时，会出现此异常“'System.StackOverflowException 类型的未处理异常'出现在 mscorlib.dll 中”，在代码的指定语句中:

    private void BindAllUsers()
    {
        SqlDataAdapter da = new SqlDataAdapter("SELECT ID, Name, Email, Password, Contact, CreatedOn, CreatedBy,CreatedIP From tbl_Users",con);
        DataSet ds = new DataSet();
        da.Fill(ds);       <------(Error occurs in this line)
        gdv_Users.DataSource = ds;
        gdv_Users.DataBind();

    }

RowDataBoundEvent 处理程序是:

    protected void gdv_Users_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        e.Row.Cells[0].Style["Cursor"] = "hand";
        e.Row.Cells[0].ToolTip = "Click Here";
        e.Row.Cells[0].Attributes.Add("onclick","window.open('Details.aspx'?ID=" + e.Row.Cells[0].Text.ToString()+"'Details';'width = 735,height= 350,left = 220,top = 300,resizable = 0,scrollbars = 0,status = no')");
    }

BindAllUser 函数在这里被调用:

 protected void Page_Load(object sender, EventArgs e)
{
    BindAllUsers();
    BindDropDown();

}

试试这个:

        private void BindAllUsers()
    {
        using (SqlConnection con = new SqlConnection("connection string"))
        {
            con.Open();
            SqlCommand command = new SqlCommand();
            command.Connection = con;
            command.CommandText = "SELECT ID, Name, Email, Password, Contact, CreatedOn, CreatedBy,CreatedIP From tbl_Users";
            SqlDataReader dr = command.ExecuteReader();
            if (dr.HasRows)
            {
                gdv_Users.DataSource = ds;
                gdv_Users.DataBind();
            }
        }

    }
