我正在使用在旧的 C# 帖子中找到的一些代码来使用 VB.net 将 DAO 插入到 Access 中。我运行代码来插入数字,它运行良好。但是,当我尝试date
在哈希之间插入一个字符串时,我得到一个Data type conversion error
. 我看了一下,但看不到如何更改记录集字段的数据类型以接受字符串/日期。
这是代码:
Dim dbEngine As New dao.DBEngine
Dim db As dao.Database = dbEngine.OpenDatabase(DataDirectoryName & DatabaseName)
Dim rs As dao.Recordset = db.OpenRecordset(TableName)
Dim myFields As dao.Field() = New dao.Field(FieldNames.Count - 1) {}
For k As Integer = 0 To FieldNames.Count - 1
myFields(k) = rs.Fields(FieldNames(k))
Next
dbEngine.BeginTrans()
For i As Double = 0 To Data.Rows - 1
rs.AddNew()
For k As Integer = 0 To FieldNames.Count - 1
rs.Fields(k).Value = Data.Value(k, i)
rs.Fields(FieldNames(k)).Value = Data.Value(k, i)
myFields(k).Value = Data.Value(k, i)
Next
rs.Update()
Next
dbEngine.CommitTrans()
rs.Close()
db.Close()
这是一行数据:
(0) = "74"
(1) = "#01 February 2012 00:02:00#"
(2) = "40"
(3) = "130"
(4) = "60"
'Data' 是一个自定义类,它是一个list (of list (of string))
.
