Exists Property

In This Topic

Determines whether an attribute actually exists

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Overridable ReadOnly Property Exists As Boolean

'Usage
 
Dim instance As DicomAttribute
Dim value As Boolean
 
value = instance.Exists

public virtual bool Exists {get;}

public:
virtual property bool Exists {
   bool get();
}

Remarks

This property returns True if this attribute exists within the Image/DataSet.

If an attempt is made to access a non-existent element of a DicomAttributeCollection, then no error is generated, but the element item returned is a unique "error element", which has an Exists property of False, and returns a Value of Null.

Requirements

Target Platforms: .NET CLR 4.0 or higher
