public string GetUserDelegationSharedAccessSignature (Microsoft.Azure.Storage.UserDelegationKey delegationKey, Microsoft.Azure.Storage.Blob.SharedAccessBlobPolicy policy, Microsoft.Azure.Storage.Blob.SharedAccessBlobHeaders headers = default, Microsoft.Azure.Storage.SharedAccessProtocol? protocols = default, Microsoft.Azure.Storage.IPAddressOrRange ipAddressOrRange = default);

member this.GetUserDelegationSharedAccessSignature : Microsoft.Azure.Storage.UserDelegationKey * Microsoft.Azure.Storage.Blob.SharedAccessBlobPolicy * Microsoft.Azure.Storage.Blob.SharedAccessBlobHeaders * Nullable<Microsoft.Azure.Storage.SharedAccessProtocol> * Microsoft.Azure.Storage.IPAddressOrRange -> string
