Exception Property (_UANodeElementCollectionResult)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.OperationModel.ComTypes Namespace > _UANodeElementCollectionResult Interface : Exception Property
Gets or sets the information about the reason of the failure of the operation.
Syntax
'Declaration
 
<CanBeNullAttribute()>
Property Exception As Exception
'Usage
 
Dim instance As _UANodeElementCollectionResult
Dim value As Exception
 
instance.Exception = value
 
value = instance.Exception
[CanBeNull()]
Exception Exception {get; set;}
[CanBeNull()]
property Exception^ Exception {
   Exception^ get();
   void set (    Exception^ value);
}

Property Value

Null reference if the operation has succeeded, or a non-null System.Exception if the operation has failed.
Remarks

If you only need to test that the operation has succeeded, you can also use the OpcLabs.BaseLib.OperationModel.OperationResult.Succeeded property.

This property is not serialized into XML. Instead, OpcLabs.BaseLib.OperationModel.OperationResult.ErrorMessage is serialized. Deserializing from XML creates a base OpcLabs.BaseLib.OperationModel.OperationResult.Exception object with just the message.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
