| override [GetExtendedCodetext](../../aspose.barcode.generation/datamatrixextcodetextbuilder/getextendedcodetext/)() | Generates Extended codetext from the extended codetext list. |

## Examples

```csharp
[C#]
//Extended codetext mode

//create codetext
DataMatrixExtCodetextBuilder textBuilder = new DataMatrixExtCodetextBuilder();
codetextBuilder.AddECICodetextWithEncodeMode(ECIEncodings.Win1251, EncodeMode.Bytes, "World");
codetextBuilder.AddPlainCodetext("Will");
codetextBuilder.AddECICodetext(ECIEncodings.UTF8, "犬Right狗");
codetextBuilder.AddCodetextWithEncodeMode(EncodeMode.C40, "ABCDE");

//generate codetext
string codetext = textBuilder.GetExtendedCodetext();    

//generate
using(BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.DataMatrix, codetext))
{
    generator.Parameters.Barcode.DataMatrix.EncodeMode = EncodeMode.ExtendedCodetext;
	generator.Save("test.bmp");
}
```
