Person person = new Person(); person.SetField("Age", 30);
Entity record = new Entity("account"); record.Id = new Guid("4E4C4249-9519-EA11-A811-000D3AF486A4"); record.SetField("name", "New Account Name");In this example, we create a new "account" entity record object and then set its "name" field to "New Account Name" using the SetField method. The record's unique identifier (GUID) is also set to an existing account's GUID so that we can modify an existing record instead of creating a new one. In summary, the System Entity SetField method in C# allows developers to modify the value of fields on entity instances, making it a useful tool for working with data in various applications.
