Question

I have a Sql Server 2008 R2 connection string that looks like

  <add name="DBConnectionString"
providerName="System.Data.SqlClient"
connectionString="Data Source=AYZ;Initial Catalog=AYZ;User ID=AYZ;Password=AYZ;"/>

When trying to create a new instance of SQLDatabase using EnterpriseLibrary.Data I get the above error.

connString =ConnectionStrings.ConnectionStrings["ConnectionString"];
Database objDB = new SqlDatabase(connString);

The detailed exception is as follows :

System.FormatException was unhandled by user code
  Message=Invalid character in a Base-64 string.
  Source=mscorlib

The connection string had to encryted to work. The team working on the project used base64encode.org to encode the string.

OTHER TIPS

You're missing a " at the end of the connection string property. It should be:

<add name="ConnectionStringName"
    providerName="System.Data.SqlClient"
    connectionString="Data Source=ServerName\InstanceName;Initial Catalog=DatabaseName;"/>
