 Q:

How to declare a variable in the app.config file?

I am working on a Windows application.
I have a form with labels like
HOST:
UserName:
Password:

How I can declare the connection string in the app.config file so that it takes the initial catalog, userID and password as variables that I can use in further to check the user whether which database the user wants to get connected with the entered userID and password.
I am using SQL Server 2008 and Visual C# 2008 Express Edition.

A:

As I'm reading your question, you want to have a generic connection string that you want to inject username/password variables into. To do that you would need to have a key with this format:
<add name="myDBKey" connectionString="Data Source=myDB;Initial Catalog={0};Persist Security Info=True;User ID={1};Password={2}" providerName="System.Data.SqlClient"/>

Then in your code, you would need to have these variables declared and assigned, and then use String.Format to complete it.
string dbCatalog = "myCatalog";
string dbUser = "myUser";
string dbPW = "myPW";

string myDBConnectionString = String.Format(
    ConfigurationManager.ConnectionStrings["myDBKey"].ConnectionString,
    dbCatalog, dbUser, dbPW);

This will inject your variables into the string.

A:

There is a <connectionString> section to the app.config file.  
<connectionStrings>
    <add name="MyDatabase" connectionString="Data Source=sqlserver,1433;Network Library=DBMSSOCN;Initial Catalog=MyDatabase;User ID=xxx;Password=xxxx;" />
  </connectionStrings>

For your Host, User ID and Password, you can define these in the <appSettings> section.

 A: 

 As I'm reading your doubt, you want to have a generic connection string that you want to inject username / password variables into. To do that you would need to have a key with this format: 
 < add name="myDBKey " connectionString="Data Source = myDB;Initial Catalog={0};Persist Security Info = True;User ID={1};Password={2 } " providerName="System. Data. SqlClient"/ > 

 Then in your code, you would need to have these variables declare and assigned, and then use String. Format to dispatch it. 
 chain dbCatalog = " myCatalog "; 
 chain dbUser = " myUser "; 
 string dbPW = " myPW "; 

 string myDBConnectionString = String. Format (
     ConfigurationManager. ConnectionStrings["myDBKey"].ConnectionString, 
     dbCatalog, dbUser, dbPW); 

 This will inject your variables into the string. 

 A: 

 There is a < connectionString > section to the app.config file.
