# Membuat kebijakan terkelola IAM dari JSON
<a name="iam-policies-create-json"></a>

Contoh ini menunjukkan cara menggunakan AWS SDK untuk .NET untuk membuat kebijakan [terkelola IAM dari dokumen kebijakan](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies) yang diberikan di JSON. Aplikasi membuat objek klien IAM, membaca dokumen kebijakan dari file, dan kemudian membuat kebijakan.

**catatan**  
Untuk contoh dokumen kebijakan di JSON, lihat [pertimbangan tambahan](#iam-policies-create-json-additional) di akhir topik ini.

Bagian berikut menyediakan cuplikan dari contoh ini. [Kode lengkap untuk contoh](#iam-policies-create-json-complete-code) ditampilkan setelah itu, dan dapat dibangun dan dijalankan apa adanya.

Cuplikan berikut membuat kebijakan terkelola IAM dengan nama dan dokumen kebijakan yang diberikan.

Contoh [di akhir topik ini](#iam-policies-create-json-complete-code) menunjukkan cuplikan ini digunakan.

```
    //
    // Method to create an IAM policy from a JSON file
    private static async Task<CreatePolicyResponse> CreateManagedPolicy(
      IAmazonIdentityManagementService iamClient, string policyName, string jsonFilename)

      return await iamClient.CreatePolicyAsync(new CreatePolicyRequest{
        PolicyName = policyName,
        PolicyDocument = File.ReadAllText(jsonFilename)});
