Question

我是C Sharp编程新手。我收到了错误。

Script Component在用户代码中遇到异常：Object 引用未设置为对象的实例。在 ScriptMain.Input0_ProcessInputRow（Input0Buffer Row）at UserComponent.Input0_ProcessInput（Input0Buffer Buffer）at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.ProcessInput（的Int32 inputID，PipelineBuffer buffer）

这是我的代码如下

using System;
using System.Data;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;
using Microsoft.SqlServer.Dts.Runtime;


[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute]
public class ScriptMain : UserComponent
{

    public override void Input0_ProcessInputRow(Input0Buffer Row)
    {
        int iEx = 0;
        int iPr = 0;
        int iPa = 0;
        int iSch = 0;
        int iTim=0;
        int iTime = 0;
        int tryCount=1;
        SC_819162ba1fcf40f686f8181327002472.csproj.WebReference.Service s = new SC_819162ba1fcf40f686f8181327002472.csproj.WebReference.Service();
        SC_819162ba1fcf40f686f8181327002472.csproj.WebReference.LicenseUsage[] l = SC_819162ba1fcf40f686f8181327002472.csproj.WebReference.LicenseUsage[10];
        l =null;
        while (tryCount<=3)
        {
            try
            {   l = s.GetProductPeakUsage(Row.salesforceidstring, Row.StartDatestring, Row.EndDatestring);
                break;
            }
            catch (Exception e)
            {
                tryCount = tryCount + 1;
                if (tryCount > 3)
                {
                    bool pbCancel = false;
                    this.ComponentMetaData.FireError(9999, "Error-Failed the 3rd time", e.ToString(), "", 0, out pbCancel);
                }

            }
        }

        for (int i = 0; i < l.Length; i++)
        {
            if (l[i].Product == SC_819162ba1fcf40f686f8181327002472.csproj.WebReference.Product.Pr)
                iPr = l[i].ActiveSeats;
            if (l[i].Product == SC_819162ba1fcf40f686f8181327002472.csproj.WebReference.Product.Sch)
                iSch = l[i].ActiveSeats;
            if (l[i].Product == SC_819162ba1fcf40f686f8181327002472.csproj.WebReference.Product.Pa)
                iPa = l[i].ActiveSeats;
            if (l[i].Product == SC_819162ba1fcf40f686f8181327002472.csproj.WebReference.Product.Ex)
                iEx = l[i].ActiveSeats;
            if (l[i].Product == SC_819162ba1fcf40f686f8181327002472.csproj.WebReference.Product.Time)
                iTime = l[i].ActiveSeats;
            if (l[i].Product == SC_819162ba1fcf40f686f8181327002472.csproj.WebReference.Product.Tim)
                iTim = l[i].ActiveSeats;
        }
        Row.Ex = iEx;
        Row.Pr = iPr;
        Row.Sch = iSch;
        Row.Pa = iPa;
        Row.Time = iTime;
        Row.Tim=iTim;

    }

}

有人可以帮我怎么调试这个？我知道我的输入值为空值。如何绕过此逻辑中的空值
