How to add an ampersand for a value in a ASP.net/C# app config file value

To add an ampersand for a value in an ASP.NET/C# app config file value, you need to escape the ampersand character with the XML entity reference "&". This is necessary because ampersands are reserved characters in XML and cannot be used directly.

For example, suppose you want to set a connection string in your app config file that contains an ampersand in the password field:

 <connectionStrings> <add name="MyConnection" connectionString="Data Source=myServer;Initial Catalog=myDB;User ID=myUsername;Password=my&Password123;" providerName="System.Data.SqlClient" /> </connectionStrings>

In this case, you would need to escape the ampersand in the password field by replacing it with "&":

 <connectionStrings> <add name="MyConnection" connectionString="Data Source=myServer;Initial Catalog=myDB;User ID=myUsername;Password=my&Password123;" providerName="System.Data.SqlClient" /> </connectionStrings>

This way, the ampersand will be properly interpreted by the XML parser and your connection string will be valid.
