## ListLevel.GetEffectiveValue method

Reports the string representation of the [`ListLevel`](../) object for the specified index of the list item. Parameters specify the [`NumberStyle`](../../../aspose.words/numberstyle/) and an optional format string used when Custom is specified.

```csharp
public static string GetEffectiveValue(int index, NumberStyle numberStyle, 
    string customNumberStyleFormat)
```

| Parameter | Type | Description |
| --- | --- | --- |
| index | Int32 | The index of the list item (must be in the range from 1 to 32767). |
| numberStyle | NumberStyle | The [`NumberStyle`](../../../aspose.words/numberstyle/) of the [`ListLevel`](../) object. |
| customNumberStyleFormat | String | The optional format string used when Custom is specified (e.g. "a, ç, ĝ, ..."). In other cases, this parameter must be `null` or empty. |

### Return Value

The string representation of the [`ListLevel`](../) object, described by the *numberStyle* parameter and the *customNumberStyleFormat* parameter, in the list item at the position determined by the *index* parameter.

### Exceptions

| exception | condition |
| --- | --- |
| ArgumentException | *customNumberStyleFormat* is `null` or empty when the *numberStyle* is custom.-or- *customNumberStyleFormat* is not `null` or empty when the *numberStyle* is non-custom.-or- *customNumberStyleFormat* is invalid. |
| ArgumentOutOfRangeException | index is out of range. |

## Examples

Shows how to get the format for a list with the custom number style.

```csharp
Document doc = new Document(MyDir + "List with leading zero.docx");

ListLevel listLevel = doc.FirstSection.Body.Paragraphs[0].ListFormat.ListLevel;

string customNumberStyleFormat = string.Empty;

if (listLevel.NumberStyle == NumberStyle.Custom)
    customNumberStyleFormat = listLevel.CustomNumberStyleFormat;

Assert.That(customNumberStyleFormat, Is.EqualTo("001, 002, 003, ..."));

// We can get value for the specified index of the list item.
Assert.That(ListLevel.GetEffectiveValue(4, NumberStyle.LowercaseRoman, null), Is.EqualTo("iv"));
Assert.That(ListLevel.GetEffectiveValue(5, NumberStyle.Custom, customNumberStyleFormat), Is.EqualTo("005"));
```
