对比一下字段名和字段类型，应该可以猜出是什么吧

或者自己增加几个字段看看type是那个数字就行了

.type的值是数字,每个值对应一种数据类型

还是不对我的数据表是.dbf
.type 的类型数字是 10 或 8

看看
Public Sub TypeX()

Dim rstEmployees As ADODB.Recordset
Dim fldLoop As ADODB.Field
Dim strCnn As String

' Open recordset with data from Employee table.
strCnn = "Provider=sqloledb;" & _
"Data Source=srv;Initial Catalog=pubs;User Id=sa;Password=; "
Set rstEmployees = New ADODB.Recordset
rstEmployees.Open "employee", strCnn, , , adCmdTable

Debug.Print "Fields in Employee Table:" & vbCr

' Enumerate Fields collection of Employees table.
For Each fldLoop In rstEmployees.Fields
Debug.Print " Name: " & fldLoop.Name & vbCr & _
" Type: " & FieldType(fldLoop.Type) & vbCr
Next fldLoop

End Sub

Public Function FieldType(intType As Integer) As String

Select Case intType
Case adChar
FieldType = "adChar"
Case adVarChar
FieldType = "adVarChar"
Case adSmallInt
FieldType = "adSmallInt"
Case adUnsignedTinyInt
FieldType = "adUnsignedTinyInt"
Case adDBTimeStamp
FieldType = "adDBTimeStamp"
End Select

End Function

试试
Private Sub Command3_Click()
Dim i As Integer
For i = 0 To Data1.Recordset.Fields.Count - 1
MsgBox Data1.Recordset.Fields(i).Type
MsgBox Data1.Recordset.Fields(i).Name
MsgBox Data1.Recordset.Fields(i).Size
Next
End Sub
