Remarks
Enumerating the collection in C# or Microsoft Visual Basic
A ColumnDefinitionCollection is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable<ColumnDefinition> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable with a ColumnDefinition constraint.
Properties
| Size |
Gets the size (count) of the collection. |
Methods
| Append(ColumnDefinition) |
Adds a new item to the collection. |
| Clear() |
Removes all items from the collection. |
| First() |
Returns the iterator for iteration over the items in the collection. |
| GetAt(UInt32) |
Returns the ColumnDefinition located at the specified index. |
| GetMany(UInt32, ColumnDefinition[]) |
Retrieves multiple elements in a single pass through the iterator. |
| GetView() |
Gets an immutable view into the collection. |
| IndexOf(ColumnDefinition, UInt32) |
Retrieves the index of the specified item. |
| InsertAt(UInt32, ColumnDefinition) |
Inserts the specified item at the specified index. |
| RemoveAt(UInt32) |
Removes the item at the specified index. |
| RemoveAtEnd() |
Removes the last item in the collection. |
| ReplaceAll(ColumnDefinition[]) |
Initially clears the collection, then inserts the provided array as new items. |
| SetAt(UInt32, ColumnDefinition) |
Sets the value at the specified index to the ColumnDefinition value specified. |
