我有以下存储过程，我必须从中获取数据：

   EXECUTE [dbo].[StationHealthStatusSummary2]
            @LineId varchar(100),        // 5,9,10
            @MeasurementDt datetime,    //2012/06/06
            @Ntotal Int output,
            @N0 int output,
            @N1 int output,
            @N2 int output,
            @N3 int output,
            @N4 int output,
            @N5 int output,
            @N6 int output,
            @N7 int output,
            @N8 int output,
            @N9 int output,
            @N10 int output,
            @N11 int output,
            @N12 int output,
            @N13 int output,
            @N14 int output,
            @N15 int output,
            @N16 int output
       GO

现在我可以将参数发送到LineID和Measurement日期如下：

SqlConnection sql = new SqlConnection(@"Data Source=(local)\SQLEXPRESS;Initial Catalog=iComs;Persist Security Info=True;User ID=sa;Password=Password);

SqlCommand getData = new SqlCommand("StationHealthStatusSummary2", sql);

SqlDataAdapter da = new SqlDataAdapter(getData);

getData.CommandType = CommandType.StoredProcedure;
getData.Parameters.Add(new SqlParameter("@LineId", Lines));
getData.Parameters.Add(new SqlParameter("@MeasurementDt", date1));

SqlParameter ParamaterNtotal = new SqlParameter();
ParamaterNtotal.ParameterName = "@Ntotal";
ParamaterNtotal.SqlDbType = SqlDbType.Int;
ParamaterNtotal.Direction = ParameterDirection.Output;
getData.Parameters.Add(ParamaterNtotal);

sql.Open();

getData.ExecuteNonQuery();

现在我可以获取 的值NTotal并将其分配给 Teechart (PieSlice)，但是如何获取 的值@N0..@N16？

我有一些代码可能会让你对我想要完成的工作有所了解。

int NTotal = int.Parse(getData.Parameters["@Ntotal"].Value.ToString());

if (GetVariantVariableI(getData.Parameters[0].Value) = 0)
{               
    for (c = 1; c <= 18; c++)
    { 
        Nvl = GetVariantVariableI(getData.Parameters[2+c].Value);

        switch(c)
        {
            case 1:
                NTotal = Nvl;
                break;

            case 2:
            case 3:
            case 4:
            case 5:
            case 6:
            case 7:
            case 8:
            case 9:
            case 10:
            case 11:                           
            case 12:                            
            case 13:                           
            case 14:                           
            case 15:                            
            case 16:                           
            case 17:
            case 18:
            case 19:
            case 20:
                cstatus = c-2;
                NPieValues[cstatus] = Nvl;
                break;
   }   

   string SliceName;
   int NUsed;

   NUsed = 0;

   for(i=0;i<=16;i++)
   {
      NUsed = NUsed + NPieValues[i];
   }

   if (NUsed < NTotal)
   {
       Chart1.Series[0].Add(NTotal - NUsed);
       slice1.Title = "Not Connected";
       slice1.Add();
       slice1.Color = System.Drawing.Color.Silver;
   }

   if (NUsed > NTotal)
   {
      NPieValues[7] = NPieValues[7]-(NUsed-NTotal);
   }

   for (i=0;i<=16;i++)
   {
     if (NPieValues[i]>0)
     {
         switch(i)
         {
            case 0: SliceName ="Green"; 
                    break;

                     break;
            default:
                     SliceName ="?";
         }
         switch(i)
         {
          case 0: clr = "System.Drawing.Color.Green";
                 break;
          case 1:clr = "System.Drawing.Color.Yellow";
                 break;
          case 2:clr = "System.Drawing.Color.Orrange";
                 break;
          case 3:clr = "System.Drawing.Color.Red";
                 break;
          case 4:
          case 5:
          case 8:clr = "System.Drawing.Color.Purple";
                 break;
          case 6:clr = "System.Drawing.Color.Black";
                 break;
          case 7:clr = "System.Drawing.Color.Gray";
                 break;;
          case 9:clr = "System.Drawing.ColorTranslator.FromHtml('#E0671F')";
                 break;
          case 10:clr = "System.Drawing.ColorTranslator.FromHtml('#BA4EC2')";
                 break;
          case  11:clr = "System.Drawing.ColorTranslator.FromHtml('#FF8000')";
                 break;
          case  12:clr =  "System.Drawing.ColorTranslator.FromHtml('#BF4093')";
                 break;
          case  13:clr = "System.Drawing.Color.SkyBlue";
                 break;
          case 14:clr = "System.Drawing.Color.Aqua";
                 break;
          case 15:clr = "System.Drawing.ColorTranslator.FromHtml('#BFBFFF')";
                 break;                 
          case 16:clr = "System.Drawing.Color.MedGray";
                 break;
             default : clr = "System.Drawing.Color.White";
                 break;              
         }
      slice1.Add(NPieValues[i],SliceName,clr);
     }

 }
            }
        }

    }

现在，在获得所有这些值之后，它必须填充饼图。

请，任何帮助将不胜感激，如果我太含糊，请告诉我。

谢谢

您已添加@Ntotal为输出参数，为什么不添加所有其他参数？

SqlParameter n = new SqlParameter();
n.ParameterName = "@N0";
n.SqlDbType = SqlDbType.Int;
n.Direction = ParameterDirection.Output;
getData.Parameters.Add(n);

然后，您可以像使用@Ntotal. 此外，如果您愿意，您可以按名称检索值，而不是遍历它们。

谢谢。我想通了......在我发送参数后如下：

    SqlParameter Paramater0 = new SqlParameter();
        Paramater0.ParameterName = "@N0";
        Paramater0.SqlDbType = SqlDbType.Int;
        Paramater0.Direction = ParameterDirection.Output;
        getData.Parameters.Add(Paramater0);

然后我获取值并将其声明为 var，如下所示：

     int N0 = int.Parse(getData.Parameters["@N0"].Value.ToString());

最后将该 int 声明为图表上的一个切片，如下所示：

     slice1.Add(N0, "Green", System.Drawing.Color.Green);

感谢您的帮助@mgnoonan :)
