```

## Methods

| Method | Description |
| --- | --- |
| [AddCodetextWithEncodeMode](./addcodetextwithencodemode/)(DataMatrixEncodeMode, System::String) | Adds codetext with defined encode mode to the extended codetext items |
| [AddECICodetext](../extcodetextbuilder/addecicodetext/)(ECIEncodings, System::String) | Adds codetext with Extended Channel Identifier |
| [AddECICodetextWithEncodeMode](./addecicodetextwithencodemode/)(ECIEncodings, DataMatrixEncodeMode, System::String) | Adds codetext with Extended Channel Identifier with defined encode mode |
| [AddPlainCodetext](../extcodetextbuilder/addplaincodetext/)(System::String) | Adds plain codetext to the extended codetext items |
| virtual [Clear](../extcodetextbuilder/clear/)() | Clears extended codetext items |
| [ExtCodetextBuilder](../extcodetextbuilder/extcodetextbuilder/)() |  |
| [GetExtendedCodetext](./getextendedcodetext/)() override | Generates Extended codetext from the extended codetext list. |
## Remarks


Extended codetext generator for 2D DataMatrix barcodes for ExtendedCodetext Mode of EncodeMode


```cpp
[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");
}
```
