-- [求助]谁能帮忙翻译一下代码的含义
刚开始接触，哪位高工能帮我翻译一下语句，看了好久没看懂。附件有例子。Dim dt As DataTable = DataTables("认证报名表")
Dim Result As DialogResult
Result = MessageBox.Show("确定要导入吗?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question)
If Result = DialogResult.Yes Then
Dim dlg As New OpenFileDialog
dlg.Filter = "Excel文件|*.xls"
dlg.MultiSelect = True \'允许选择多个文件
If dlg.ShowDialog =DialogResult.OK Then
Dim Book As New XLS.Book(dlg.FileName)
Dim Sheet As XLS.Sheet = Book.Sheets("认证报名表")
dt.ResumeRedraw()
dt.StopRedraw()
\'systemready = False
Dim nms As New Dictionary(Of String, Integer)
Dim dic As new Dictionary(Of DataRow, Integer)
Dim ls As new List(Of Integer)
For c As Integer = 0 To sheet.Cols.Count - 1
If dt.DataCols.Contains(sheet(0,c).Text.replace(" ", "")) Then
nms.Add(sheet(0,c).Text.replace(" ", ""), c)
End If
Next
For n As Integer = 1 To Sheet.Rows.Count -1
Dim sfzhm As String = sheet(n,nms("身份证号码")).Text
If sfzhm = "" Then Continue For
Dim dr As DataRow = dt.Find("身份证号码 = \'" & sfzhm & "\'")
If dr Is Nothing Then
ls.add(n)
Else
dic.Add(dr, n)
End If
Next
For Each key As DataRow In dic.Keys
For Each m As String In nms.keys
If dt.DataCols(m).IsBoolean Then
If Sheet(dic(key),nms(m)).Text = "" OrElse Sheet(dic(key),nms(m)).Text = "False" OrElse Sheet(dic(key),nms(m)).Value = 0 Then
key(m) = False
Else
key(m) = True
End If
Else If dt.DataCols(m).Expression > "" Then
\'表达式列
Else If dt.DataCols(m).IsNumeric Then
key(m) = val(Sheet(dic(key),nms(m)).Value)
Else If dt.DataCols(m).IsDate Then
Dim d As Date
If Date.TryParse(Sheet(dic(key),nms(m)).Value, d)
key(m) = d
End If
Else
key(m) = Sheet(dic(key),nms(m)).Value
End If
Next
Next
For Each l As Integer In ls
Dim ndr As DataRow = dt.AddNew
For Each m As String In nms.keys
If dt.DataCols(m).IsBoolean Then
If Sheet(l,nms(m)).Text = "" OrElse Sheet(l,nms(m)).Text = "False" OrElse Sheet(l,nms(m)).Value = 0 Then
ndr (m) = False
Else
ndr (m) = True
End If
Else If dt.DataCols(m).Expression > "" Then
\'表达式列
Else If dt.DataCols(m).IsNumeric Then
ndr (m) = val(Sheet(l,nms(m)).Value)
Else If dt.DataCols(m).IsDate Then
Dim d As Date
If Date.TryParse(Sheet(l,nms(m)).Value, d)
ndr (m) = d
End If
Else
ndr (m) = Sheet(l,nms(m)).Value
End If
Next
Next
dt.ResumeRedraw()
\'systemready = True
End If
End If

这段代码是合并数据的一段代码，不需要看懂。大体思路是：如果表里面有相同的身份证，就修改数据，否则，就新增数据。
你只需要修改红色代码和表名，其余不变。
Dim sfzhm As String = sheet(n,nms("身份证号码")).Text
If sfzhm = "" Then Continue For
Dim dr As DataRow = dt.Find("身份证号码 = \'" & sfzhm & "\'")
