我正在尝试在文本框中显示您选择的“收件人”的序列号，但出现此错误：
System.ArgumentException: Cannot bind to the property or column RecipientSNo on the DataSource.
我用不同的查询（相同的代码，只是将列名从'recipient'更改为'issuer'）对另一个文本框执行此操作，只是为了调试并且它可以工作！我再次向“收件人”尝试了它，但它仍然不起作用；不起作用。我的代码：
query("SELECT RecipientSNo FROM Recipient WHERE CONCAT(FirstName, ' ', MI, '. ', LastName) = '" & ReceiverName.Text & "';")
Try
adapter = New MySqlDataAdapter(CommandText, ServerString)
table = New DataTable
Dim ds As New DataSet
Dim bs As BindingSource
adapter.Fill(ds, "recipient")
bs = New BindingSource(ds, "recipient")
DataBindings.Clear()
ReceiverSNo.DataBindings.Add("text", bs, "ReceipientSNo")
Catch ex As Exception
MsgBox(ex.ToString)
End Try
disconnect()
这是来自“发行者”的代码，它正在工作：
query("SELECT IssuerSNo FROM Issuer WHERE CONCAT(FirstName, ' ', MI, '. ', LastName) = '" & IssuerName.Text & "';")
Try
adapter = New MySqlDataAdapter(CommandText, ServerString)
table = New DataTable
Dim ds As New DataSet
Dim bs As BindingSource
adapter.Fill(ds, "armorer")
bs = New BindingSource(ds, "armorer")
IssuerSNo.DataBindings.Clear()
IssuerSNo.DataBindings.Add("text", bs, "ArmorerSNo")
Catch ex As Exception
MsgBox(ex.ToString)
End Try
disconnect()
我刚刚处理了这段代码并更改了文本框和列名，但它已经不起作用了.. 似乎是什么问题？我已经仔细检查了我的表名和列名。
