# 를 사용하여 Secrets Manager 보안 암호 값 가져오기 SDK for .NET
<a name="retrieving-secrets-net-sdk"></a>

애플리케이션에서 `GetSecretValue` 또는 SDK`BatchGetSecretValue`를 호출하여 보안 암호를 검색할 수 있습니다. AWS SDKs 그러나 클라이언트 측 캐싱을 사용하여 보안 암호 값을 캐싱하는 것이 좋습니다. 보안 암호 캐싱은 속도를 향상시키고 비용을 절감합니다.

.NET 애플리케이션의 경우 [Secrets Manager .NET 기반 캐싱 구성 요소](retrieving-secrets_cache-net.md)를 사용하거나 [https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/SecretsManager/TGetSecretValueRequest.html](https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/SecretsManager/TGetSecretValueRequest.html) 또는 [https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/SecretsManager/TBatchGetSecretValueRequest.html](https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/SecretsManager/TBatchGetSecretValueRequest.html)를 사용하여 SDK를 직접 호출합니다.

다음 코드 예시는 `GetSecretValue`의 사용 방법을 보여 줍니다.
