# GetHostSetECIDInfo
### int GetHostSetECIDInfo(int lMsgId, ref uint\[] arrInt, ref string\[] arrStr)
Host가 S2F15W메시지를 이용하여 ECID의 ECVALUE를 변경 시도할 때 수신한 SECS메시지의 ECID 배열과 ECValues를 읽음
Parameters
| | |
|---|
| Name | Type | Description |
| lMsgId | int | 수신한 Message의 ID |
| arrInt | uint[] | ECID를 저장할 배열 |
| arrStr | string[] | ECV를 저장할 배열 |
```csharp
uint[] arrECIDs = null; // ECID들을 담을 배열
string[] arrNewValues = null; // 변경될 값들을 담을 배열
// 1. GetHostSetECIDInfo 호출 (ref 키워드로 배열 참조 전달)
// 함수 내부에서 요청 개수에 맞게 배열이 자동으로 할당(new)됩니다.
int nResult = m_gem.GetHostSetECIDInfo(lMsgId, ref arrECIDs, ref arrNewValues);
// 2. 결과 확인
if (nResult >= 0 && arrECIDs != null)
{
Console.WriteLine($"총 {arrECIDs.Length}개의 EC 변경 요청이 확인되었습니다.");
for (int i = 0; i < arrECIDs.Length; i++)
{
Console.WriteLine($"[{i+1}] ECID: {arrECIDs[i]}, New Value: {arrNewValues[i]}");
// 여기서 각 ECID별로 실제 장비 파라미터 업데이트 로직 수행
}
}
else
{
Console.WriteLine($"EC 정보 일괄 추출 실패. 에러 코드: {nResult}");
}
```
