To create a connection to a ServiceNow data source, the ADO.NET Provider can be used through the C1ServiceNowConnection class. This expects to be passed a connection string as an argument, which can be either:

• Generated using the C1ServiceNowConnectionStringBuilder class by specifying individual statements.
• Constructed manually by writing the connection string directly.

Connection string generation

The following code shows how C1ServiceNowConnectionStringBuilder class can be used to configure the connection string for ServiceNow and consumed by the C1ServiceNowConnection class to create a connection to the server. Here, you can query the data.

//Create connection string using C1ServiceNowConnectionStringBuilder
connBuilder.Username = @"*******";
connBuilder.Password = @"*******";
connBuilder.OAuthClientId = @"*******";
connBuilder.OAuthClientSecret = @"*******";
connBuilder.OAuthTokenEndpoint = @"http://****/****/****";
connBuilder.Url = @"http://****/****/****";

//Create and establish a connection
C1ServiceNowConnection conn = new C1ServiceNowConnection(connBuilder)

Connection string literal

Alternatively, the connection string can be written directly as a string literal like in the code example below. A similar approach can be implemented in other DataConnectors for ADO.NET provider.

//Define connection string
string connectionString = @"Username= *******; Password= *******; Oauth Client Id= *******; 
Oauth Client Secret= *******; Oauth Token Endpoint= http://****/****/****; Url= http://****/****/****";
//Create and establish a connection
C1ServiceNowConnection conn = new C1ServiceNowConnection(connectionString);
