C#中存储过程的调用

SqlConnection con = new SqlConnection("连接字符串");
SqlCommand cmd = new SqlCommand("SelectManStudent", con);
SqlParameter parm = new SqlParameter("@Sex", SqlDbType.NVarChar);
parm.Value = '男';//此处传性别
cmd.Parameters.Add(parm);
cmd.CommandType = CommandType.StoredProcedure;
con.Open();
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();

sda.Fill(ds);

con.Close();

//ds就是查出来的结果集
