如何在asp.net mvc3中将字符串作为整数保存到数据库中 [英] how to save string into database as integer in asp.net mvc3

问题描述

嗨
我在使用dropdownlist的过程中建立了网格，

如果我从下拉列表中选择任何项目，则应根据其ID将其保存为整数.


鉴于我已将其视为字符串

在模型中，我将其视为字符串

但在控制器查询中，我需要将其从字符串转换为短字符串"


例如:res.cat_id = c.category;

但我遇到错误，将其更改为整数，而我做错了，我无法理解.


请任何人给我样品或相关类型的解决方案.

谢谢，

解决方案

您需要使用Int32.Parse()或Int32.TryParse()方法将字符串转换为整数.

Sukanya，尽管您应该在初始阶段就已经做好了DB设计的工作.但是到目前为止，如果您走得很远，我建议您从控制器转换为所需格式的所需数据，然后发送插入查询.

使用convert.toint和.tostring()将数据转换为所需的格式.

You need to use the Int32.Parse() or Int32.TryParse() method, to convert from string to integer.

Sukanya, though you should have had taken care of DB design in the initial stage. but as of now if you have gone very far I would suggest you to convert the required data in required format from controller and then send the insert query.

use convert.toint and .tostring() to convert the data into ur desired format.
