c# web.config server - How to get Database Name from Connection String using SqlConnectionStringBuilder

3 Answers

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;


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;
password attachdbfilename odbc

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?)
