## BorderCollection::idx_get(Aspose::Words::BorderType) method


Retrieves a [Border](../../border/) object by border type.

```cpp
System::SharedPtr<Aspose::Words::Border> Aspose::Words::BorderCollection::idx_get(Aspose::Words::BorderType borderType)
```


| Parameter | Type | Description |
| --- | --- | --- |
| borderType | Aspose::Words::BorderType | A [BorderType](../../bordertype/) value that specifies the type of the border to retrieve. |
## Remarks


Note that not all borders are present for different document elements. This method throws an exception if you request a border not applicable to the current object.

## Examples



Shows how to decorate text with borders and shading. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

System::SharedPtr<Aspose::Words::BorderCollection> borders = builder->get_ParagraphFormat()->get_Borders();
borders->set_DistanceFromText(20);
borders->idx_get(BorderType::Left)->set_LineStyle(LineStyle::Double);
borders->idx_get(BorderType::Right)->set_LineStyle(LineStyle::Double);
borders->idx_get(BorderType::Top)->set_LineStyle(LineStyle::Double);
borders->idx_get(BorderType::Bottom)->set_LineStyle(LineStyle::Double);

System::SharedPtr<Aspose::Words::Shading> shading = builder->get_ParagraphFormat()->get_Shading();
shading->set_Texture(TextureIndex::TextureDiagonalCross);
shading->set_BackgroundPatternColor(System::Drawing::Color::get_LightCoral());
shading->set_ForegroundPatternColor(System::Drawing::Color::get_LightSalmon());

builder->Write(u"This paragraph is formatted with a double border and shading.");
doc->Save(get_ArtifactsDir() + u"DocumentBuilder.ApplyBordersAndShading.docx");
```

## BorderCollection::idx_get(int32_t) method


Retrieves a [Border](../../border/) object by index.

```cpp
System::SharedPtr<Aspose::Words::Border> Aspose::Words::BorderCollection::idx_get(int32_t index)
```


| Parameter | Type | Description |
| --- | --- | --- |
| index | int32_t | Zero-based index of the border to retrieve. |

## Examples



Shows how border collections can share elements. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

builder->Writeln(u"Paragraph 1.");
builder->Write(u"Paragraph 2.");

// Since we used the same border configuration while creating
// these paragraphs, their border collections share the same elements.
System::SharedPtr<Aspose::Words::BorderCollection> firstParagraphBorders = doc->get_FirstSection()->get_Body()->get_FirstParagraph()->get_ParagraphFormat()->get_Borders();
System::SharedPtr<Aspose::Words::BorderCollection> secondParagraphBorders = builder->get_CurrentParagraph()->get_ParagraphFormat()->get_Borders();

for (int32_t i = 0; i < firstParagraphBorders->get_Count(); i++)
{
    ASSERT_TRUE(System::ObjectExt::Equals(firstParagraphBorders->idx_get(i), secondParagraphBorders->idx_get(i)));
    ASSERT_EQ(System::ObjectExt::GetHashCode(firstParagraphBorders->idx_get(i)), System::ObjectExt::GetHashCode(secondParagraphBorders->idx_get(i)));
    ASSERT_FALSE(firstParagraphBorders->idx_get(i)->get_IsVisible());
}

for (auto&& border : System::IterateOver(secondParagraphBorders))
{
    border->set_LineStyle(LineStyle::DotDash);
}

// After changing the line style of the borders in just the second paragraph,
// the border collections no longer share the same elements.
for (int32_t i = 0; i < firstParagraphBorders->get_Count(); i++)
{
    ASSERT_FALSE(System::ObjectExt::Equals(firstParagraphBorders->idx_get(i), secondParagraphBorders->idx_get(i)));
    ASSERT_NE(System::ObjectExt::GetHashCode(firstParagraphBorders->idx_get(i)), System::ObjectExt::GetHashCode(secondParagraphBorders->idx_get(i)));

    // Changing the appearance of an empty border makes it visible.
    ASSERT_TRUE(secondParagraphBorders->idx_get(i)->get_IsVisible());
}

doc->Save(get_ArtifactsDir() + u"Border.SharedElements.docx");
```
