# Using the Lambda context object to retrieve C\# function information

When Lambda runs your function, it passes a context object to the [handler](csharp-handler.md). This object provides properties with information about the invocation, function, and execution environment.
**Context properties**
+ `FunctionName` – The name of the Lambda function.
+ `FunctionVersion` – The [version](configuration-versions.md) of the function.
+ `InvokedFunctionArn` – The Amazon Resource Name (ARN) that's used to invoke the function. Indicates if the invoker specified a version number or alias.
+ `MemoryLimitInMB` – The amount of memory that's allocated for the function.
+ `AwsRequestId` – The identifier of the invocation request.
+ `LogGroupName` – The log group for the function.
+ `LogStreamName` – The log stream for the function instance.
+ `RemainingTime` (`TimeSpan`) – The number of milliseconds left before the execution times out.
+ `Identity` – (mobile apps) Information about the Amazon Cognito identity that authorized the request.
+ `ClientContext` – (mobile apps) Client context that's provided to Lambda by the client application.
+ `Logger` The [logger object](csharp-logging.md) for the function.
You can use information in the `ILambdaContext` object to output information about your function's invocation for monitoring purposes. The following code provides an example of how to add context information to a structured logging framework. In this example, the function adds `AwsRequestId` to the log outputs. The function also uses the `RemainingTime` property to cancel an inflight task if the Lambda function timeout is about to be reached.
```
[assembly: LambdaSerializer(typeof(Amazon.Lambda.Serialization.SystemTextJson.DefaultLambdaJsonSerializer))]
namespace GetProductHandler;
public class Function
{
 private readonly IDatabaseRepository _repo;
 
 public Function()
 {
 this._repo = new DatabaseRepository();
 }
 
 public async Task<apigatewayproxyresponse> FunctionHandler(APIGatewayProxyRequest request, ILambdaContext context)
 {
 Logger.AppendKey("AwsRequestId", context.AwsRequestId);
 
 var id = request.PathParameters["id"];
 using var cts = new CancellationTokenSource();
 
 try
 {
 cts.CancelAfter(context.RemainingTime.Add(TimeSpan.FromSeconds(-1)));
 
 var databaseRecord = await this._repo.GetById(id, cts.Token);
 
 return new APIGatewayProxyResponse 
 {
 StatusCode = (int)HttpStatusCode.OK,
 Body = JsonSerializer.Serialize(databaseRecord)
 };
 }
 catch (Exception ex)
 {
 return new APIGatewayProxyResponse 
 {
 StatusCode = (int)HttpStatusCode.InternalServerError,
 Body = JsonSerializer.Serialize(new { error = ex.Message })
 };
 }
 finally
 {
 cts.Cancel();
 }
 }
}
