【ASP.NET开发】ADO.NET调用带输出参数的存储过程

public static void QueryList()
{
SqlConnection con = new SqlConnection("数据库连接字符串");
SqlCommand cmd = new SqlCommand("存储过程名称", con);
//指定命令的类型
cmd.CommandType = CommandType.StoredProcedure;

SqlParameter[] para ={
new SqlParameter("参数1",SqlDbType.Int),
new SqlParameter("参数2",SqlDbType.Int),
new SqlParameter("参数3",SqlDbType.Int),
new SqlParameter("参数4",SqlDbType.Int)

};

para[0].Value = 3;
para[1].Value = 4;
para[2].Direction = ParameterDirection.Output;  //设定参数的输出方向
para[3].Direction = ParameterDirection.Output;

cmd.Parameters.AddRange(para);// 将参数加入命令对象
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
adapter.Fill(dt);

foreach (DataRow dr in dt.Rows)
{
Console.WriteLine(dr[0].ToString());
}

int pageCount = Convert.ToInt32(cmd.Parameters[2].Value);
int rowCount = Convert.ToInt32(cmd.Parameters[3].Value);

Console.WriteLine("PageCount=" + pageCount + ",rowCount=" + rowCount);
}
