AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Returns a list of your Lambda functions. For each function, the response includes the function configuration information. You must use GetFunction to retrieve the code for your function.

This operation requires permission for the lambda:ListFunctions action.

If you are using the versioning feature, you can list all of your functions or only $LATEST versions. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases.

Note:

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginListFunctions and EndListFunctions. For Unity the operation does not take CancellationToken as a parameter, and instead takes AmazonServiceCallback<ListFunctionsRequest, ListFunctionsResponse> and AsyncOptions as additional parameters.

Namespace: Amazon.Lambda
Assembly: AWSSDK.Lambda.dll

Exceptions

ExceptionCondition
InvalidParameterValueException One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception. You will also get this exception if you have selected a deprecated runtime, such as Node v0.10.42.
ServiceException The AWS Lambda service encountered an internal error.
