## Constructors

### OpcCertificateStoreInfo

Initializes a new instance of the [OpcCertificateStoreInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opccertificatestoreinfo/) class using the `path` and `type` specified.

<div class="api-signature" data-lang="csharp">

```csharp
public OpcCertificateStoreInfo(string path, OpcCertificateStoreType type)
```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet
Public Sub New(path As String, type As OpcCertificateStoreType)
```

</div>

**Parameters**

| Name | Type | Description |
|---|---|---|
| `path` | [String](https://learn.microsoft.com/dotnet/api/system.string) | The path of the certificate store. |
| `type` | [OpcCertificateStoreType](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opccertificatestoretype/) | The purpose of the certificate store. |

**Exceptions**

**Remarks**

The [PathType](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opccertificatestoreinfo/members#pathtype) is determined from the `path`: a path which starts with "LocalMachine\\", "CurrentUser\\", "User\\" or "Service\\" is a store of the operating system ([System](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opccertificatestorepathtype/#system)), any other path a directory ([Directory](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opccertificatestorepathtype/#directory)).
