Connection String

Hi you can declare constring and connection object globally as below

First you need to add key in the app.config file as shown below

<br />
<br />
   <appSettings><br />
<br />
<add key="DbConnectionString" value="database=pubs;user Id=sa;password=sa"/><br />
<br />
    </appSettings><br />

then in the C# code behind file include the namespace
using System.Configuration;

then read the connection string from app.config as below

static readonly string DB_CONN_STRING = ConfigurationManager.AppSettings["DbConnectionString"];
