C# connect to database and list the databases [duplicate]

Answer 1

You can use SqlConnection.GetSchema:

using(var con = new SqlConnection("Data Source=Yourserver; Integrated Security=True;"))
{
    con.Open();
    DataTable databases = con.GetSchema("Databases");
    foreach (DataRow database in databases.Rows)
    {
        String databaseName = database.Field("database_name");
        short dbID = database.Field("dbid");
        DateTime creationDate = database.Field("create_date");
    }
} 

SQL Server Schema Collections (ADO.NET)

To determine the list of supported schema collections, call the GetSchema method with no arguments, or with the schema collection name "MetaDataCollections". This will return a DataTable with a list of the supported schema collections, the number of restrictions that they each support, and the number of identifier parts that they use.
