Question

错误：没有为'Public Overridable Overloads Function Fill的参数'SiteId'指定参数（dataTable为LCSRDBDateSet.SampleDataTable，SiteId As String）As Integer'

我该如何解决这个问题？请帮忙。这不是我自己的代码。我正在研究其他的代码。

If String.IsNullOrEmpty(reportFilter) Then daSample.SetWhereClause(String.Format("cdr_site_id = '{0}' AND cdr_datetime BETWEEN '{1}' AND '{2}' AND cdr_extension_no IN({3}) AND cdr_call_type_id IN({4}) GROUP BY cdr_extension_id", siteId, startDateTime, endDateTime, callClass, callType))

Else
    Dim filters2 = reportFilter.Split(",")
    Dim ta2 As New LCSRDBDataSetTableAdapters.SampleTableAdapter
    Dim dt2 = ta.GetData(siteId)

If filters.Count = dt.Rows.Count Then
    daSample.SetWhereClause(String.Format("cdr_site_id = '{0}' AND cdr_datetime BETWEEN '{1}' AND '{2}' AND cdr_extension_no IN({3}) AND cdr_call_type_id IN({4}) GROUP BY cdr_extension_id", siteId, startDateTime, endDateTime, callClass, callType))
Else
    daSample.SetWhereClause(String.Format("cdr_site_id = '{0}' AND cdr_datetime BETWEEN '{1}' AND '{2}' AND cdr_extension_no IN({3}) AND cdr_call_type_id IN({4}) GROUP BY cdr_extension_id", siteId, startDateTime, endDateTime, callClass, callType))
End If

End If

daSample.Fill(dtSample)
rdsSample.Name = "LCSRDBDataSet_Sample"
rdsSample.Value = dtSample
rvScreen.LocalReport.DataSources.Add(rdsSample)

我认为你有一些错误：

  If String.IsNullOrEmpty(reportFilter) Then      daSample.SetWhereClause(String.Format("cdr_site_id = '{0}' AND cdr_datetime BETWEEN '{1}' AND '{2}' AND cdr_extension_no IN({3}) AND cdr_call_type_id IN({4}) GROUP BY cdr_extension_id", siteId, startDateTime, endDateTime, callClass, callType))

  Else
      Dim filters2 = reportFilter.Split(",")
      Dim ta2 As New LCSRDBDataSetTableAdapters.SampleTableAdapter
      Dim dt2 = ta.GetData(siteId)

  If filters.Count = dt.Rows.Count Then
      daSample.SetWhereClause(String.Format("cdr_site_id = '{0}' AND cdr_datetime BETWEEN '{1}' AND '{2}' AND cdr_extension_no IN({3}) AND cdr_call_type_id IN({4}) GROUP BY cdr_extension_id", siteId, startDateTime, endDateTime, callClass, callType))
  Else
      daSample.SetWhereClause(String.Format("cdr_site_id = '{0}' AND cdr_datetime BETWEEN '{1}' AND '{2}' AND cdr_extension_no IN({3}) AND cdr_call_type_id IN({4}) GROUP BY cdr_extension_id", siteId, startDateTime, endDateTime, callClass, callType))
  End If

  End If

1。首先不是逃避纠正，
2.你将vb与C＃混合 3.您的错误产生于：“cdr_site_id ='{0}'和cdr_datetime BETWEEN'{1}'
因为未定义{0}和{1}或isNull
