也许How to quickly copy tables from an ODBC source to MS Access within a C# project 的这段代码可能会有所帮助:
您需要放置的 VB 函数
进入 MS Access 非常简单,并且
基本上调用 TransferDatabase
通过将 DSN 传递给方法(指向
到源数据库),源
表名和目标表名。这
代码如下:
Public Function Import(dsnName As String, sourceTableName As String, targetTableName As String)
‘ if the table already existsm, delete it.
On Error GoTo CopyTable
DoCmd.DeleteObject acTable, targetTableName
CopyTable:
DoCmd.TransferDatabase _
acImport, _
"ODBC Database", _
"ODBC;DSN=" + dsnName, _
acTable, _
sourceTableName, _
targetTableName
End Function
将 VBA 更改为读取 acLink 而不是 acImport 应该允许链接。
然后是 C# 代码:
object accessObject = null;
try
{
accessObject = Activator.CreateInstance(Type.GetTypeFromProgID("Access.Application"));
accessObject.GetType().InvokeMember(
"OpenCurrentDatabase",
System.Reflection.BindingFlags.Default System.Reflection.BindingFlags.InvokeMethod,
null,
accessObject,
new Object[] { "AccessDbase.mdb" });
accessObject.GetType().InvokeMember(
"Run",
System.Reflection.BindingFlags.Default System.Reflection.BindingFlags.InvokeMethod,
null,
accessObject,
new Object[] { "Import", "DSN Name", "Source table name", "Target table name" });
accessObject.GetType().InvokeMember(
"CloseCurrentDatabase",
System.Reflection.BindingFlags.Default System.Reflection.BindingFlags.InvokeMethod,
null,
accessObject,
null);
MessageBox.Show("Copy succeeded.");
}
catch (Exception ex)
{
string message = ex.Message;
while (ex.InnerException != null)
{
ex = ex.InnerException;
message += "\r\n----\r\n" + ex.Message;
}
MessageBox.Show(message);
}
finally
{
if (accessObject != null)
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(accessObject);
accessObject = null;
}
}

我对 c# 无能为力,但这里有一些 VBScript 链接了一个表
一个 MDB 到另一个。
strLinkFile = "C:\Docs\Link.mdb"
strAccessFile = "C:\Docs\LTD.mdb"
'Create Link... '
Set cn = CreateObject("ADODB.Connection")
cn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & strAccessFile & ";" & _
"Persist Security Info=False"
Set adoCat = CreateObject("ADOX.Catalog")
Set adoCat.ActiveConnection = cn
Set adoTbl = CreateObject("ADOX.Table")
Set adoTbl.ParentCatalog = adoCat
adoTbl.Name = "LinkTable"
adoTbl.properties("Jet OLEDB:Link Datasource") = strLinkFile
adoTbl.properties("Jet OLEDB:Link Provider String") = "MS Access"
adoTbl.properties("Jet OLEDB:Remote Table Name") = "Table1"
adoTbl.properties("Jet OLEDB:Create Link") = True
'Append the table to the tables collection '
adoCat.Tables.Append adoTbl
