c# - password - server name in connection string




How to get Database Name from Connection String using SqlConnectionStringBuilder (5)

A much simpler alternative is to get the information from the connection object itself. For example:

IDbConnection connection = new SqlConnection(connectionString);
var dbName = connection.Database;

Similarly you can get the server name as well from the connection object.

DbConnection connection = new SqlConnection(connectionString);
var server = connection.DataSource;

I never want to split connection string using string manipulation and get server,database,uid and password.

I read the following link and read the accepted answer , I found that is the best way to get userid and password out from connection string, but what about Database Name?

Right way to get username and password from connection string?

How to get Database Name from Connection String using SqlConnectionStringBuilder. (does the DataSource is the Server name?)



You can use InitialCatalog Property or builder["Database"] works as well. I tested it with different case and it still works.


You can use the provider-specific ConnectionStringBuilder class (within the appropriate namespace), or System.Data.Common.DbConnectionStringBuilder to abstract the connection string object if you need to. You'd need to know the provider-specific keywords used to designate the information you're looking for, but for a SQL Server example you could do either of these two things:

System.Data.SqlClient.SqlConnectionStringBuilder builder = new System.Data.SqlClient.SqlConnectionStringBuilder(connectionString);

string server = builder.DataSource;
string database = builder.InitialCatalog;

or

System.Data.Common.DbConnectionStringBuilder builder = new System.Data.Common.DbConnectionStringBuilder();

builder.ConnectionString = connectionString;

string server = builder["Data Source"] as string;
string database = builder["Initial Catalog"] as string;

string connectString = "Data Source=(local);" + "Integrated Security=true";

SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(connectString);

Console.WriteLine("builder.InitialCatalog = " + builder.InitialCatalog);
