Sql 从存储过程获取记录时出错

我有代码从存储过程中获取数据

我只需要存储过程中的记录。但是现在我在使用DataAccess代码的类中遇到了错误：

SelectCommand.Connection property has not been initialized. fill data adapter

我只想使用分页跟踪所有行：

namespace SpidiWeb.App_Code.Helper
{
    public class DataAccess
    {
        public string mstr_ConnectionString;
        public SqlConnection mobj_SqlConnection;
        public SqlCommand mobj_SqlCommand;
        public int mint_CommandTimeout = 30;

        public void GetConnection(string cnn_type, string dbname)
        {
            try
            {
                if (cnn_type == "W")
                {
                    string Cnn_Str = "";

                    //string ServerName = "SHREE-PC";
                    //string DBUserName = string.Empty;
                    //string DBPassword = string.Empty;

                    string ServerName = ConfigurationManager.AppSettings["SERVER"];
                    string DBUserName = ConfigurationManager.AppSettings["UID"] ?? string.Empty;
                    string DBPassword = ConfigurationManager.AppSettings["PASSWORD"] ?? string.Empty;
                    string Database = dbname;
                    DBPassword += "c#" + Convert.ToChar(49);

                    //Cnn_Str = "Server=" + ServerName + ";User Id=" + DBUserName + ";Password=" + DBPassword + ";Initial Catalog=" + Database;
                    Cnn_Str = "Server=" + ServerName + ";Initial Catalog=" + Database +";Integrated Security=True";

                    mstr_ConnectionString = Cnn_Str;
                }
                else if (cnn_type == "S")
                {
                    string Cnn_Str = "";

                    //string ServerName = "SHREE-PC";
                    //string DBUserName = string.Empty;
                    //string DBPassword = string.Empty;

                    string ServerName = ConfigurationManager.AppSettings["SERVER"];
                    string DBUserName = ConfigurationManager.AppSettings["UID"] ?? string.Empty;
                    string DBPassword = ConfigurationManager.AppSettings["PASSWORD"] ?? string.Empty;
                    string Database = "NEWSMSLOG_" + dbname;
                    DBPassword += "c#" + Convert.ToChar(49);

                    //Cnn_Str = "Server=" + ServerName + ";User Id=" + DBUserName + ";Password=" + DBPassword + ";Initial Catalog=" + Database;
                    Cnn_Str = "Server=" + ServerName + ";Initial Catalog=" + Database + ";Integrated Security=True";
                    mstr_ConnectionString = Cnn_Str;
                }
                mobj_SqlConnection = new SqlConnection(mstr_ConnectionString);
                mobj_SqlCommand = new SqlCommand();
                mobj_SqlCommand.CommandTimeout = mint_CommandTimeout;
                mobj_SqlCommand.CommandType = CommandType.StoredProcedure;
                mobj_SqlCommand.Connection = mobj_SqlConnection;
                mobj_SqlConnection.Open();
            }
            catch (Exception ex)
            {
                throw new Exception("Error initializing data class." + Environment.NewLine + ex.Message);
            }

此代码来自我的页面：

DataAccess obj_con = new DataAccess();

{
    try
    {
        DataTable dt = new DataTable();
        int intUserId = ddl_users.SelectedItem.Text.ToString() == "All" ? 0 : Convert.ToInt32(ddl_users.SelectedValue.ToString());

        int intSenderId = ddl_sender.SelectedItem.Text.ToString() == "All" ? 0 : Convert.ToInt32(ddl_sender.SelectedValue.ToString());
        string strDeliveryId = ddl_delevery.SelectedItem.Text.ToString() == "All" ? "-1" : ddl_delevery.SelectedItem.Text.ToString();

        using (var con = obj_con.mobj_SqlConnection)
        {
            //if (con.State == ConnectionState.Closed)
            //    con.Open();
            var cmd = new SqlCommand();
            cmd.Parameters.AddWithValue("intUserID", intUserId);

            if (ddl_account.SelectedItem.Text.ToString() == "All")
            {
                cmd.Parameters.AddWithValue("intAccType", DBNull.Value);
            }
            else

            }

                cmd.Parameters.AddWithValue("strTBNM", DateTime.Now.Date.ToString("ddMMyy"));
            }

            cmd.Parameters.AddWithValue("PageIndex", 1);
            cmd.Parameters.AddWithValue("PageSize", 1000);
            cmd.Parameters.Add("RecordCount", SqlDbType.Int).Direction = ParameterDirection.Output;
            cmd.Connection = con;
            cmd.CommandText = "dbo.Report_ViewCombineReport";
            cmd.CommandType = CommandType.StoredProcedure;

            SqlDataAdapter ad = new SqlDataAdapter(cmd);
            ad.SelectCommand = cmd;
            ad.Fill(dt); // Error Occurs here Fill: SelectCommand.Connection property has not been initialized.
            egrd.DataSource = dt;
            egrd.DataBind();
        }
    }
    catch (Exception ex)

您并没有传递到SqlCommand对象的连接，而是像下面这样在参数中传递它

var cmd = new SqlCommand("Your query", con);

或者，您也可以将其设置为

cmd.Connection = con;

我们应该发布所有与代码相关的数据。错误消息丢失。请将问题更新为details@KerenCaelen-请现在检查一下
