I am using the SchemaComparison object to compare a database schema with a dacpac file, once the comparison is completed I generate a script with the changes, now I would like to know how can I execute the script to update a database:

var comparison = new SchemaComparison(sourceDacpac, targetDatabase);
SchemaComparisonResult comparisonResult = comparison.Compare();
var script = comparisonResult.GenerateScript(databaseName);
if(script.Success)
{ // Execute script }

What I have tried:

I tried this code, but I am getting an error SqlException: Incorrect syntax near ':', I think this is coming from the first lines of the script

GO
:setvar DatabaseName "NAME"

using(Microsoft.Data.SqlClient.SqlConnection connection = new Microsoft.Data.SqlClient.SqlConnection(myConnection))
{
Server server = new Server(new ServerConnection(connection));
server.ConnectionContext.StatementTimeout = 0;
server.ConnectionContext.ExecuteNonQuery(script);
}
