Dim dlg As New OpenFileDialog \'定义一个新的OpenFileDialog
dlg.Filter= "excle|*.xlsx" \'设置筛选器
Dim c As Integer = 0
If dlg.ShowDialog = DialogResult.Ok Then \'如果用户单击了确定按钮
Dim Book As New XLS.Book(dlg.FileName)
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables("工资总表导入").StopRedraw()

For sr As Integer = 1 To sheet.Rows.Count -1
Dim r As Row = Tables("工资总表导入").AddNew
For sc As Integer = 0 To sheet.Cols.Count -1
For Each dc As DataCol In DataTables("工资总表导入").DataCols
If dc.Name = sheet(0,sc).Value Then
r(dc.name) = sheet(sr,sc).Value
End If
Next
Next
c = c +1
Next
Tables("工资总表导入").ResumeRedraw()
MessageBox.Show("导入完成,共导入" & c & "条记录")
End If

求这段代码优化，数据导入时间过长

以下是引用Hyphen在2016/8/16 9:02:00的发言：

Dim dlg As New OpenFileDialog \'定义一个新的OpenFileDialog
dlg.Filter= "excle|*.xlsx" \'设置筛选器

If dlg.ShowDialog = DialogResult.Ok Then \'如果用户单击了确定按钮
Dim Book As New XLS.Book(dlg.FileName)
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Dim t As Table = Tables("工资总表导入")
t.StopRedraw()
Dim c As Integer = t.Rows.Count
Dim dict As new Dictionary(of Integer,String)
For sc As Integer = 0 To sheet.Cols.Count -1
If t.Cols.Contains(sheet(0,sc).Value) Then
dict.Add(sc,sheet(0,sc).Value)
End If
Next

For sr As Integer = 1 To sheet.Rows.Count -1
Dim r As Row = t.AddNew
For Each i As Integer In dict.Keys
r(dict(i)) = sheet(sr,i).Value
Next
Next
t.ResumeRedraw()
MessageBox.Show("导入完成,共导入" & t.Rows.Count - c & "条记录")
End If

Dictionary 居然还有这个代码。。。。
但是这段代码我复制上去了报错

错误提示：列“”不属于表工资导入。工资总表导入我改成了工资导入，表重新复制了下源表。。

2楼代码应该没问题，上传实例说明。
