公司数据库从32位的SqlServer 2005升级到64位的SqlServer 2008 R2后，无法再像原来通过Link Server连接VFP同步数据，因此考虑用代码程序从VFP数据库中读取所需数据然后再插入到SqlServer数据库中，下面贴出该C#代码以备忘或供有需要者参考。
private void GetDataFromVFP()
{
OdbcConnection conn = null ;
try
{
string strOdbcConn = @"Driver={Microsoft Visual FoxPro Driver};SourceType=DBF;SourceDB=D:/a/b;Exclusive=No;Collate=Machine;";
string strInsertConn = @"User id=a;Password=b;Database=c;Server=d;Connect Timeout=50;Max Pool size=200;Min pool Size=5" ;
conn = new OdbcConnection ();
conn.ConnectionString = strOdbcConn;
conn.Open();
string strTableName = "" ;
for (int i = -8; i < 0; i++)
{
strTableName = "FOLIO" + DateTime .Today.AddDays(i).ToString("dd");
string sql = string .Format(@"select a,b,c from {0}", strTableName);
OdbcDataAdapter da = new OdbcDataAdapter(sql, conn);
DataTable dt = new DataTable();
da.Fill(dt);
SqlBulkCopy bulkCopy = new SqlBulkCopy(strInsertConn);
bulkCopy.BulkCopyTimeout = 1800000;
bulkCopy.DestinationTableName = "strTableName";
bulkCopy.WriteToServer(dt);
}
}
catch
{ }
finally
{
if (conn != null )
{
conn.Close();
}
}
}
