推荐答案

如果您正在使用SQL Server，那么它正是它的设计目标：多个用户。

您可能需要更改的唯一内容是连接字符串，具体取决于如何编码。

If you are using SQL Server, then that is exactly what it is designed for: multiple users.
The only thing you may have to change is the connection string, depending on how you coded it.

你好，

如果机器通过局域网内部连接，你可以回答你的问题。

只需通过IIS在一台机器上托管应用程序请参阅此如何部署IIS中的Web应用程序

将path ...distribute复制到其他计算机并检查Intranet可访问性。



对于Sql server连接：



请允许其他用户访问数据库并检查其他机器的可访问性。



例如:)

Hello,
To Answer your question if the machines are connected internally through LAN it is possible.
Just host the application in one machine through IIS Refer this How To Deploy a Web App in IIS
Copy the path..distribute to other machines and check the Intranet accessibility.

For Sql server connection :

Pls provide access to other users to the database and check the accessibility from other machines .

eg:)

- Create user windows Authentication
CREATE LOGIN [YourDomainName] FROM WINDOWS
WITH DEFAULT_DATABASE = [YourDatabase];
GO
-- Add User to first database
USE YourDatabaseHere;
CREATE USER X FOR LOGIN [YourDomainNameJohnJacobs];
EXEC sp_addrolemember 'db_datareader', 'X'
EXEC sp_addrolemember 'db_datawriter', 'X'
Go

-- Create user for SQL Authentication
CREATE LOGIN X WITH PASSWORD = 'X'
,DEFAULT_DATABASE = [YourDatabase]
GO
-- Add User to first database
USE YourDatabaseHere;
CREATE USER X FOR LOGIN X;
EXEC sp_addrolemember 'db_datareader', 'X'
EXEC sp_addrolemember 'db_datawriter', 'X'
GO

对于你对connectionstring的查询：在Web.config中请这样的代码

For your query for connectionstring:In the Web.config pls code like this

<connectionStrings>
	
    <add  name="yourconnectionstring"  connectionString="Data Source=yourserverName\SQLEXPRESS;Initial Catalog=yourDatabaseName;Integrated Security=True"  providerName="System.Data.SqlClient" />
  </connectionStrings>

Wala！你的工作已经完成！
