## Triggers

OnRun

## Called by

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 3007 "DotNet_String"](../codeunit/3007.md) (6 calls: `FromCharArray → GetArray`, `Split → GetArray`, `Split → SetArray`, …)
- [Codeunit 3026 "DotNet_Encoding"](../codeunit/3026.md) (6 calls: `GetBytes → GetArray`, `GetBytes → SetArray`, `GetBytesWithOffset → GetArray`, …)
- [Codeunit 3035 "DotNet_Buffer"](../codeunit/3035.md) (4 calls: `BlockCopy → GetArray`, `ByteLength → GetArray`, `GetByte → GetArray`, …)
- [Codeunit 1259 "Certificate Management"](../codeunit/1259.md) (3 calls: `ConvertCertToDotNetFromBase64 → SetArray`, `ReadCertFromBlob → SetArray`, `ReadCertFromStream → SetArray`)
- [Codeunit 3032 "DotNet_BinaryReader"](../codeunit/3032.md) (2 calls: `ReadBytes → SetArray`, `ReadChars → SetArray`)
- [Codeunit 3034 "DotNet_Stream"](../codeunit/3034.md) (2 calls: `Read → GetArray`, `Write → GetArray`)
- [Codeunit 3043 "DotNet_X509Certificate2"](../codeunit/3043.md) (2 calls: `Export → SetArray`, `X509Certificate2 → GetArray`)
- [Codeunit 3009 "DotNet_MemoryStream"](../codeunit/3009.md) (1 call: `ToArray → SetArray`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC28

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "DotNet_Array")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
