Web API Basic Operations Sample (C#)

  • Artikel

This .NET 6.0 sample demonstrates how to perform common data operations using the Dataverse Web API.

This sample uses the common helper code in the WebAPIService class library (C#).

Note

This sample implements the Dataverse operations and console output detailed in Web API Basic Operations Sample and uses the common C# constructs described in Web API Samples (C#).

Prerequisites

These are required to build and run this sample:

  • Microsoft Visual Studio 2022.
  • Access to Dataverse with privileges to perform data operations.

How to run this sample

  1. Clone or download the PowerApps-Samples repository.

  2. Locate the /dataverse/webapi/C#-NETx/BasicOperations/ folder.

  3. Open the BasicOperations.sln file using Visual Studio 2022

The code for this sample is here: PowerApps-Samples/dataverse/webapi/C#-NETx/BasicOperations/Program.cs

Demonstrates

This sample has five regions:

Section 1: Basic Create and Update operations

Operations:

  • Create a contact record.
  • Update the contact record.
  • Retrieve the contact record.
  • Update a single property of the contact record.
  • Retrieve a single property of the contact record.

Section 2: Create record associated to another

Operations: Associate a new record to an existing one.

Operations: Create the following entries in one operation: an account, its associated primary contact, and open tasks for that contact. These entity types have the following relationships:

Accounts
    |---[Primary] Contact (N-to-1)
        |---Tasks (1-to-N)

Section 4: Associate and Disassociate entities

Operations:

  • Add a contact to the account contact_customer_accounts collection.
  • Remove a contact from the account contact_customer_accounts collection.
  • Associate a security role to a user using the systemuserroles_association collection.
  • Remove a security role for a user using the systemuserroles_association collection.

Section 5: Delete sample entities

Operations: A reference to each record created in this sample was added to a list as it was created. This section loops through that list and deletes each record.

Clean up

By default this sample deletes all the records created in it. If you want to view created records after the sample is completed, change the deleteCreatedRecords variable to false and you'll be prompted to decide if you want to delete the records.
