在读取器关闭时无效尝试调用Read，base {System.SystemException} = {“读取器关闭时无效尝试调用深度。”}

Question

在使用存储过程中的数据读取器检索数据时获取此异常。 读取器关闭时无效尝试调用深度。读取器关闭时无效尝试调用读取，base {System.SystemException} = {“读取器关闭时无效尝试调用深度。”

base {System.SystemException} = {"Invalid attempt to call HasRows when reader is closed."}
base {System.SystemException} = {"Invalid attempt to call FieldCount when reader is closed."}
  public DataSet FilteredGetProductsSearch(string ProductName,  int PageSize,int PageIndex)
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("ProductId");
            dt.Columns.Add("ProductPriceId");
