[API] Object reference not set to an instance of an object.

Here is the event code. Could anyone have a check? Thank you very much.


DateTime before, after;
TimeSpan diff;
double timediff = 0;

int rowcount = 0;
string rowcontent = null;

public void HTTPActivity5_OnBeforeExecuteStepEvent(object sender, STActivityBaseEventArgs args)
GetDataSource("api!Result").ImportFromExcelFile(@"C:\Users\uft\Desktop\api.xls", "Result", true);
rowcontent = GetDataSource("api!Result").GetValue(rowcount, "recipient").ToString();
while (String.IsNullOrWhiteSpace(rowcontent) == false)
   rowcontent = GetDataSource("api!Result").GetValue(rowcount, "recipient").ToString();
before = DateTime.UtcNow;


public void HTTPActivity5_OnCodeCheckPointEvent(object sender, CheckpointEventArgs args)
if (this.HTTPActivity5.StatusCode == 200)
GetDataSource("api!Result").SetValue(rowcount, "checkpoint", "TRUE");
GetDataSource("api!Result").SetValue(rowcount, "checkpoint", "FALSE");

public void HTTPActivity5_OnAfterExecuteStepEvent(object sender, STActivityBaseEventArgs args)
after = DateTime.UtcNow;
diff = after.Subtract(before);
timediff = diff.TotalMilliseconds;
this.HTTPActivity5.Report("timediff", timediff.ToString());
this.HTTPActivity5.Report("before", before.ToString("MM/dd/yyyy HH:mm:ss"));

GetDataSource("api!Result").SetValue(rowcount, "date", before.ToString("MM/dd/yyyy"));
GetDataSource("api!Result").SetValue(rowcount, "time", before.ToString("HH:mm:ss"));
GetDataSource("api!Result").SetValue(rowcount, "login_transaction", timediff.ToString());
