网上找到的一个保存数数到access的例子

呵呵，我这有现成的，c#+access的：
private void load()
{
OleDbConnection conn=new OleDbConnectio(Common.ComClass.ComClass.GetConnStr());
OleDbCommand cmd=new OleDbCommand("select top 1 * from 签名",conn);
OleDbDataReader dr;

conn.Open();
dr=cmd.ExecuteReader();
if(dr.Read())
{
Byte[] byteBLOBData = new Byte[0];
byteBLOBData = (Byte[])dr.GetValue(0);
MemoryStream stmBLOBData = new MemoryStream(byteBLOBData);
s1.Image=Image.FromStream(stmBLOBData);

byteBLOBData = (Byte[])dr.GetValue(1);
stmBLOBData = new MemoryStream(byteBLOBData);
s2.Image=Image.FromStream(stmBLOBData);
}
dr.Close();
conn.Close();
}

private void button3_Click(object sender, System.EventArgs e)
{
if(str1==null) return;

OleDbConnection conn=new OleDbConnection(Common.ComClass.ComClass.GetConnStr());
OleDbCommand cmd=new OleDbCommand("update 签名 set 负责人=@Image",conn);
string strBLOBFilePath=str1;

FileStream fsBLOBFile = new FileStream(strBLOBFilePath,FileMode.Open, FileAccess.Read);
Byte[] bytBLOBData = new Byte[fsBLOBFile.Length];
fsBLOBFile.Read(bytBLOBData, 0, bytBLOBData.Length);
fsBLOBFile.Close();

OleDbParameter prm=new OleDbParameter("@Image",OleDbType.Binary,bytBLOBData.Length,
ParameterDirection.Input,false,0,0,null,DataRowVersion.Current,bytBLOBData);
cmd.Parameters.Add(prm);

conn.Open();
cmd.ExecuteNonQuery();
conn.Close();

ComClass.Msg("成功保存技术负责人签名!");

}
自已修改一下。
