SDK samples
Code samples from the Azure SDK development team demonstrate API usage. You can find these samples on GitHub.
Sample | Description |
---|---|
Hello world - synchronous | Demonstrates how to create a client, authenticate, and handle errors using synchronous methods |
Hello world - asynchronous | Demonstrates how to create a client, authenticate, and handle errors using asynchronous methods |
Service-level operations | Demonstrates how to create indexes, indexers, data sources, skillsets, and synonym maps. This sample also shows you how to get service statistics and how to query an index |
Index operations | Demonstrates how to perform an action on existing index, in this case getting a count of documents stored in the index |
FieldBuilderIgnore | Demonstrates a technique for working with unsupported data types |
Indexing documents (push model) | Push model indexing, where you send a JSON payload to an index on a service |
Encryption key sample | Demonstrates using a customer-managed encryption key to add an extra layer of protection over sensitive content |
Vector search sample | Shows you how to index a vector field and perform vector search using the Azure SDK for .NET |
Doc samples
Code samples from the Azure AI Search team demonstrate features and workflows. All of the following samples are referenced in tutorials, quickstarts, and how-to articles that explain the code in detail. You can find these samples in Azure-Samples/azure-search-dotnet-samples and in Azure-Samples/search-dotnet-getting-started on GitHub.
