Array Bounds cannot appear in type specifier
提问by Rara Arar
I keep having this error within a line of my code and I can't seem to fix it.
我一直在我的代码行中遇到这个错误，我似乎无法修复它。
Here is my code:
这是我的代码：
con.Open()
Dim dt As DataTable
Dim ds As DataSet
ds.Tables.Add(dt)
Dim da As OleDbDataAdapter
da = New OleDbDataAdapter("Select From * product info", con)
da.Fill(dt)
Dim newRow As DataRow = dt.NewRow
With newRow
.Item("Product Name:") = txtItemName.Text
.Item("Description") = txtDescription.Text
.Item("Quantity:") = txtItemCount.Text
.Item("Type:") = cmbItemType.Text
.Item("Date Received:") = txtDate.Text
.Item("Barcode:") = txtBarcode.Text
.Item("Price:") = txtPrice.Text
End With
dt.Rows.Add(newRow)
Dim cb As OleDbCommandBuilder(da)
da.Update(dt)
con.Close()
In the Dim cb As OleDbCommandBuilder(da)line I get the error on the da
在这一Dim cb As OleDbCommandBuilder(da)行中，我收到了错误da
回答by Steve
You have mixed the initialization and declaration of the variable cb.
The correct syntax to use is
您混合了变量cb的初始化和声明。
要使用的正确语法是
Dim cb As OleDbCommandBuilder = new OleDbCommandBuilder(da)
or
或者
Dim cb As OleDbCommandBuilder 'declaration
cb = new OleDbCommandBuilder(da) 'initialization
or (as explained by Konrad below)
或（如下面的康拉德所解释的）
Dim cb As New OleDbCommandBuilder(da)
