Represents a collection of designers.


Namespace:  System.ComponentModel.Design
Assembly:  System (in System.dll)

[PermissionSetAttribute(SecurityAction.LinkDemand, Name = "FullTrust")]
[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)]
[PermissionSetAttribute(SecurityAction.InheritanceDemand, Name = "FullTrust")]
public class DesignerCollection : ICollection, 

The DesignerCollection type exposes the following members.

Public methodDesignerCollection(IDesignerHost[])Initializes a new instance of the DesignerCollection class that contains the specified designers.
Public methodDesignerCollection(IList)Initializes a new instance of the DesignerCollection class that contains the specified set of designers.

Public propertyCountGets the number of designers in the collection.
Public propertyItemGets the designer at the specified index.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetEnumeratorGets a new enumerator for this collection.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public Extension MethodAsParallelEnables parallelization of a query. (Defined by ParallelEnumerable.)
Public Extension MethodAsQueryableConverts an IEnumerable to an IQueryable. (Defined by Queryable.)
Public Extension MethodCast<TResult>Converts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)
Public Extension MethodOfType<TResult>Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.)

Explicit interface implemetationPrivate methodICollection.CopyToCopies the elements of the collection to an Array, starting at a particular Array index.
Explicit interface implemetationPrivate propertyICollection.CountGets the number of elements contained in the collection.
Explicit interface implemetationPrivate propertyICollection.IsSynchronizedGets a value indicating whether access to the ICollection is synchronized (thread safe).
Explicit interface implemetationPrivate propertyICollection.SyncRootGets an object that can be used to synchronize access to the collection.
Explicit interface implemetationPrivate methodIEnumerable.GetEnumeratorGets a new enumerator for this collection.

This collection object can store references to a set of designers.


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The following code example creates a DesignerCollection initialized with a specified array of IDesignerHost objects.

// Create a DesignerCollection using a constructor
// that accepts an array of IDesignerHost objects with 
// which to initialize the array.
DesignerCollection collection = new DesignerCollection( 
    new IDesignerHost[] { designerhost1, designerhost2 } );
