How to validate constructed FHIR resource

[shuhaibk54]

Can anyone have the code snippet or guidance where I can find the FHIR resource validation after constructing resource(faced server).?

If I understand your question correctly, you can use $validate just against the base resource. More details on how this is implemented in the FHIR server are found here: https://docs.microsoft.com/en-us/azure/healthcare-apis/fhir/validation-against-profiles

[shuhaibk54]

let us say I have created a resource object and I want validate whether the resource meets all the constraints, any code snippet where I can find resource validation in c# code.

We use Firely library to represent objects in memory and run different types of validation.
First thing is converting xml or json string into object
We use FhirJsonParser and FhirXmlParser

fhir-server/src/Microsoft.Health.Fhir.Shared.Api/Modules/FhirModule.cs

Line 73 in c677029

FhirResourceFormat.Json, (str, version, lastModified) =>

Next we check are all attributes align with spec,
We use DotNetAttributeValidation class https://github.com/microsoft/fhir-server/blob/main/src/Microsoft.Health.Fhir.Shared.Core/Features/Validation/ModelAttributeValidator.cs

If we need to conform recourse with specific profile we use Validator class.
