### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `key` | `String` | The case-sensitive name of [SyncEntity.Name](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/SyncEntity/) or [SyncEntity.Lock](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/SyncEntity/). |

### Returns

| Type | Description |
| --- | --- |
| `Object` | The value of the property selected by `key`. |

### Exceptions

| Type | Description |

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `key` | `String` | The case-sensitive name of [SyncEntity.Name](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/SyncEntity/) or [SyncEntity.Lock](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/SyncEntity/). |
| `value` | `Object` | The value to assign. A value for [SyncEntity.Lock](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/SyncEntity/) must be a [Guid](https://learn.microsoft.com/dotnet/api/system.guid); a value that is not a [string](https://learn.microsoft.com/dotnet/api/system.string) for [SyncEntity.Name](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/SyncEntity/) is assigned as [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null). |

### Exceptions

| Type | Description |
| --- | --- |
| `ColumnNotExistsException` | `key` does not match the name of a supported property. |
| `InvalidCastException` | `key` identifies [SyncEntity.Lock](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/SyncEntity/) and `value` is not [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) and is not a [Guid](https://learn.microsoft.com/dotnet/api/system.guid). |
| `NullReferenceException` | `key` identifies [SyncEntity.Lock](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/SyncEntity/) and `value` is [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null). |
