### Description

Determines the default [StreamType](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/streamtype/enumeration/llms-full.txt) used in the file `Open...` and file `Save As...` dialogboxes.

### Syntax

```csharp
public StreamType DefaultStreamType { get; set; }
```

```vbnet
Public Property DefaultStreamType As StreamType
```

### Examples

The following example treats documents without a detectable signature as WordprocessingML files. The configured base settings are then used by the appropriate load or save operation.

```csharp
loadSaveSettingsBase.DefaultStreamType = StreamType.WordprocessingML;
if (loadSaveSettingsBase is LoadSettings loadSettings)
{
    textControl.Load("template.docx", StreamType.WordprocessingML, loadSettings);
}
else if (loadSaveSettingsBase is SaveSettings saveSettings)
{
    textControl.Save("configured-document.docx", StreamType.WordprocessingML, saveSettings);
}
```

```vbnet
loadSaveSettingsBase.DefaultStreamType = StreamType.WordprocessingML
If TypeOf loadSaveSettingsBase Is LoadSettings Then
    textControl.Load("template.docx", StreamType.WordprocessingML, DirectCast(loadSaveSettingsBase, LoadSettings))
ElseIf TypeOf loadSaveSettingsBase Is SaveSettings Then
    textControl.Save("configured-document.docx", StreamType.WordprocessingML, DirectCast(loadSaveSettingsBase, SaveSettings))
End If
```
