也许该这样吧？
string c_codes = Request.QueryString["c_code"];
int len = c_codes.Length;
if (len = 4)
DA = new OleDbDataAdapter("SELECT * FROM web_file where left(c_code,4)=" + c_codes , MyConn);
else
DA = new OleDbDataAdapter("SELECT * FROM web_file where c_code=" + c_codes , MyConn);
string c_codes = Request.QueryString["c_code"];
int len = c_codes.Length;
if (len = 4)
DA = new OleDbDataAdapter("SELECT * FROM web_file where left(c_code,4)=" + c_codes , MyConn);
else
DA = new OleDbDataAdapter("SELECT * FROM web_file where c_code=" + c_codes , MyConn);
