CadRootPackage class
Represents the root package allowing working with metadata in a CAD drawing.
public abstract class CadRootPackage : RootMetadataPackage
Properties
Name | Description |
---|---|
CadPackage { get; } | Gets the CAD metadata package. |
Count { get; } | Gets the number of metadata properties. |
FileType { get; } | Gets the file type metadata package. |
Item { get; } | Gets the MetadataProperty with the specified name. |
Keys { get; } | Gets a collection of the metadata property names. |
MetadataType { get; } | Gets the metadata type. |
PropertyDescriptors { get; } | Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine. |
Methods
Name | Description |
---|---|
virtual AddProperties(Func<MetadataProperty, bool>, PropertyValue) | Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. |
Contains(string) | Determines whether the package contains a metadata property with the specified name. |
virtual FindProperties(Func<MetadataProperty, bool>) | Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well. |
GetEnumerator() | Returns an enumerator that iterates through the collection. |
virtual RemoveProperties(Func<MetadataProperty, bool>) | Removes metadata properties satisfying the specified predicate. |
override Sanitize() | Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well. |
virtual SetProperties(Func<MetadataProperty, bool>, PropertyValue) | Sets known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. This method is a combination of AddProperties and UpdateProperties . If an existing property satisfies the predicate its value is updated. If there is a known property missing in the package that satisfies the predicate it is added to the package. |
virtual UpdateProperties(Func<MetadataProperty, bool>, PropertyValue) | Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. |

Examples
This code sample shows how to read metadata of a CAD drawing.
using (Metadata metadata = new Metadata(Constants.InputDxf))
{
var root = metadata.GetRootPackage<CadRootPackage>();
Console.WriteLine(root.CadPackage.AcadVersion);
Console.WriteLine(root.CadPackage.Author);
Console.WriteLine(root.CadPackage.Comments);
Console.WriteLine(root.CadPackage.CreatedDateTime);
Console.WriteLine(root.CadPackage.HyperlinkBase);
Console.WriteLine(root.CadPackage.Keywords);
Console.WriteLine(root.CadPackage.LastSavedBy);
Console.WriteLine(root.CadPackage.Title);
