<summary>Represents a collection of <see cref="T:System.ComponentModel.EventDescriptor" /> objects.</summary>
<remarks>
<format type="text/markdown"><![CDATA[
## Remarks
<xref:System.ComponentModel.EventDescriptorCollection> is read-only; it does not implement methods that add or remove events. You must inherit from this class to implement these methods.
Using the properties available in the <xref:System.ComponentModel.EventDescriptorCollection> class, you can query the collection about its contents. Use the <xref:System.ComponentModel.EventDescriptorCollection.Count%2A> property to determine the number of elements in the collection. Use the <xref:System.ComponentModel.EventDescriptorCollection.Item%2A> property to get a specific property by index number or by name.
You can also use the <xref:System.ComponentModel.EventDescriptorCollection.Find%2A> method to get a description of the event with the specified name from the collection.
## Examples
The following code example prints all the events on a button in a text box. It requires that `button1` and `textBox1` have been instantiated on a form.

## Remarks
The <xref:System.ComponentModel.EventDescriptorCollection.Count%2A> property can be used to set the limits of a loop that iterates through a collection of objects. If the collection is zero-based, be sure to use `Count - 1` as the upper boundary of the loop.

## Examples
The following code example uses the <xref:System.ComponentModel.EventDescriptorCollection.Count%2A> property to print the number of events attached to `button1`. It requires that `button1` and `textBox1` have been instantiated on a form.

## Examples
The following code example defines the sort order for the <xref:System.ComponentModel.EventDescriptorCollection.InternalSort%2A> method. If the <xref:System.ComponentModel.EventDescriptorCollection> contains four <xref:System.ComponentModel.EventDescriptor> objects with the names `A`, `B`, `C`, and `D`, the properties of this <xref:System.ComponentModel.EventDescriptorCollection> would be sorted in the order `D`, `B`, `A`, and `C`.

<summary>Gets or sets the event with the specified index number.</summary>
<value>The <see cref="T:System.ComponentModel.EventDescriptor" /> with the specified index number.</value>
<remarks>
<format type="text/markdown"><![CDATA[
## Remarks
The index number is zero-based. Therefore, you must subtract 1 from the numerical position of a particular <xref:System.ComponentModel.EventDescriptor> to access that <xref:System.ComponentModel.EventDescriptor>. For example, to get the third <xref:System.ComponentModel.EventDescriptor>, you need to specify `myColl[2]`.
## Examples
The following code example uses the <xref:System.ComponentModel.EventDescriptorCollection.Item%2A> property to print the name of the <xref:System.ComponentModel.EventDescriptor> specified by the index number in a text box. Because the index number is zero-based, this example prints the name of the second <xref:System.ComponentModel.EventDescriptor>. It requires that `button1` and `textBox1` have been instantiated on a form.
