<P>SqlParameter賦值之后怎么添加值</P> <P>用SqlCommand我知道用add <BR>但我想問的是 &nbsp; SqlParameter <BR><BR>例如 <BR>SqlParameter &nbsp; parm &nbsp; = &nbsp; new &nbsp; SqlParameter(PARM_ORDER_ID, &nbsp; SqlDbType.Int); <BR>parm.Value &nbsp; = &nbsp; orderId; <BR><BR>之后能不能再改parm添加一個值 <BR>因為我寫了個方法是傳遞SqlParameter類型的參數 <BR>但有時要做些判斷 <BR>像 <BR>SqlParameter &nbsp; parm &nbsp; = &nbsp; new &nbsp; SqlParameter(PARM_ORDER_ID, &nbsp; SqlDbType.Int); <BR>parm.Value &nbsp; = &nbsp; orderId; <BR><BR>if(...) <BR>{ <BR>//添加一個參數 <BR>} <BR><BR>ExecuteReader(parm,.....); <BR><BR>請問應該怎么做呢</P>
