Is there any connection string parser in C#?

Question

I have a connection string and I want to be able to peek out for example \"Data Source\". Is there a parser, or do I have to search the string?

Answer 1

You can use DbConnectionStringBuilder, and you don't need any specific provider:

The following code:

var cnstr = "Data Source=data source value;Server=ServerValue";
var builder = new DbConnectionStringBuilder();
builder.ConnectionString = cnstr;
Console.WriteLine("Data Source: {0}", builder["Data Source"]);
Console.WriteLine("Server: {0}", builder["Server"]);

Outputs to console:

Data Source: data source value
Server: ServerValue

EDIT:

Since DbConnectionStringBuilder implements IDictionary you can enumerate the connection string parameters:

foreach (KeyValuePair kv in builder)
{
    Console.WriteLine("{0}: {1}", kv.Key, kv.Value);
}
