#### Parameters

`value` T

Value to remove.

#### Returns

[bool](https://learn.microsoft.com/dotnet/api/system.boolean)

True if the value was found and removed.

### RemoveAt(int) <a href="#ks_reactor_kslinkedlist_1_removeat_system_int32" id="ks_reactor_kslinkedlist_1_removeat_system_int32"></a>

Removes the value at a specified index.

```csharp
public void RemoveAt(int index)
```

#### Parameters

`index` [int](https://learn.microsoft.com/dotnet/api/system.int32)

Index of value to remove.

### RemoveCurrent() <a href="#ks_reactor_kslinkedlist_1_removecurrent" id="ks_reactor_kslinkedlist_1_removecurrent"></a>

```csharp
public bool RemoveCurrent()
```

#### Returns

[bool](https://learn.microsoft.com/dotnet/api/system.boolean)

True if a value was removed.

### ResetCurrent() <a href="#ks_reactor_kslinkedlist_1_resetcurrent" id="ks_reactor_kslinkedlist_1_resetcurrent"></a>

Sets the current iterator pointer to null to stop iterating with [Next](/reactor/api-reference/ks.reactor.md#KS_Reactor_ksLinkedList_601_Next). This will not stop [GetEnumerator](/reactor/api-reference/ks.reactor.md#KS_Reactor_ksLinkedList_601_GetEnumerator) iteration.

```csharp
public void ResetCurrent()
```
