## FieldCollection class


A collection of [Field](../field/) objects that represents the fields in the specified range. To learn more, visit the [Working with Fields](https://docs.aspose.com/words/cpp/working-with-fields/) documentation article.

```cpp
class FieldCollection : public System::Collections::Generic::IEnumerable<System::SharedPtr<Aspose::Words::Fields::Field>>
```

## Methods

| Method | Description |
| --- | --- |
| [Clear](./clear/)() | Removes all fields of this collection from the document and from this collection itself. |
| [get_Count](./get_count/)() | Returns the number of the fields in the collection. |
| [GetEnumerator](./getenumerator/)() override | Returns an enumerator object. |
| [GetType](./gettype/)() const override |  |
| [idx_get](./idx_get/)(int32_t) | Returns a field at the specified index. |
| [Is](./is/)(const System::TypeInfo\&) const override |  |
| [Remove](./remove/)(const System::SharedPtr\<Aspose::Words::Fields::Field\>\&) | Removes the specified field from this collection and from the document. |
| [RemoveAt](./removeat/)(int32_t) | Removes a field at the specified index from this collection and from the document. |
| static [Type](./type/)() |  |
## Remarks


An instance of this collection iterates fields which start fall within the specified range.

The [FieldCollection](./) collection does not own the fields it contains, rather, is just a selection of fields.

The [FieldCollection](./) collection is "live", i.e. changes to the children of the node object that it was created from are immediately reflected in the fields returned by the [FieldCollection](./) properties and methods.

## Examples



Shows how to remove fields from a field collection. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

builder->InsertField(u" DATE \\@ \"dddd, d MMMM yyyy\" ");
builder->InsertField(u" TIME ");
builder->InsertField(u" REVNUM ");
builder->InsertField(u" AUTHOR  \"John Doe\" ");
builder->InsertField(u" SUBJECT \"My Subject\" ");
builder->InsertField(u" QUOTE \"Hello world!\" ");
doc->UpdateFields();

System::SharedPtr<Aspose::Words::Fields::FieldCollection> fields = doc->get_Range()->get_Fields();

ASSERT_EQ(6, fields->get_Count());

// Below are four ways of removing fields from a field collection.
// 1 -  Get a field to remove itself:
fields->idx_get(0)->Remove();
ASSERT_EQ(5, fields->get_Count());

// 2 -  Get the collection to remove a field that we pass to its removal method:
System::SharedPtr<Aspose::Words::Fields::Field> lastField = fields->idx_get(3);
fields->Remove(lastField);
ASSERT_EQ(4, fields->get_Count());

// 3 -  Remove a field from a collection at an index:
fields->RemoveAt(2);
ASSERT_EQ(3, fields->get_Count());

// 4 -  Remove all the fields from the collection at once:
fields->Clear();
ASSERT_EQ(0, fields->get_Count());
```
