### Description

An instance of the ConditionalInstructionCollection class contains all conditional instructions in a Text Control document or part of the document represented through objects of type [ConditionalInstruction](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/conditionalinstruction/llms-full.txt). An instance of this class can be obtained with the [FormFieldCollection.ConditionalInstructions](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/formfieldcollection/conditionalinstructions-property/llms-full.txt) property. The ConditionalInstructionCollection class implements the `IEnumerable` and the `ICollection` interfaces.

### Syntax

```csharp
public class ConditionalInstructionCollection : ICollection, IEnumerable
```

```vbnet
Public Class ConditionalInstructionCollection
    Implements ICollection, IEnumerable
```

### Examples

The following example includes the conditional instruction names value from a Conditional Instruction Collection object in application diagnostics. The created object is then available to the surrounding document workflow.

```csharp
Console.WriteLine($"Conditional Instruction Names: {conditionalInstructionCollection.ConditionalInstructionNames}");
Console.WriteLine("Conditional Instruction Collection is ready for use.");
```

```vbnet
Console.WriteLine($"Conditional Instruction Names: {conditionalInstructionCollection.ConditionalInstructionNames}")
Console.WriteLine("Conditional Instruction Collection is ready for use.")
```

- [ConditionalInstructionCollection.ConditionalInstructionNames Property](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/conditionalinstructioncollection/conditionalinstructionnames-property/llms-full.txt): Gets the names of all ConditionalInstruction elements that are listed inside the collection.
- [ConditionalInstructionCollection.CopyTo Method](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/conditionalinstructioncollection/copyto-method/llms-full.txt): Copies the elements of the collection to an array, starting at a particular index.
- [ConditionalInstructionCollection.Count Property](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/conditionalinstructioncollection/count-property/llms-full.txt): Gets the number of elements contained in the collection.
- [ConditionalInstructionCollection.GetEnumerator Method](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/conditionalinstructioncollection/getenumerator-method/llms-full.txt): Returns an enumerator that can be used to iterate through the collection.

- [ConditionalInstructionCollection.GetItems Method](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/conditionalinstructioncollection/getitems-method/llms-full.txt): Gets those ConditionalInstruction elements from the collection, where at least one Condition or Instruction element references the specified FormField.
- [ConditionalInstructionCollection.IsValueValid Method](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/conditionalinstructioncollection/isvaluevalid-method/llms-full.txt): Returns a value indicating whether the value of a specific form field is marked as valid. The corresponding validation is executed by the conditions of a conditional instruction and applied by an Instruction object, that marks the related form field as valid or invalid.
