DataMatrix 條碼是由黑色和白色“單元”組成的二維條形碼，或以正方形或矩形模式排列的模塊。要編碼的信息可以是文本或數字數據。

代碼：

Step 1:創建一個BarcodeSettings實例

BarcodeSettings settings = new BarcodeSettings();

Step 2:設置條碼模塊的寬度

settings.X = 2;

Step 3:將條碼類型設置為DataMatrix

settings.Type = BarCodeType.DataMatrix;

Step 4:設置數據并顯示文字

settings.Data = "ABC 123456789ABC 123456789ABC 123456789";
settings.Data2D = "ABC 123456789ABC 123456789ABC 123456789";

Step 5:將DataMatrix符號形狀設置為正方形

settings.DataMatrixSymbolShape = DataMatrixSymbolShape.Square;

Step 6:根據設置生成條形碼圖像并以.png格式保存

BarCodeGenerator generator = new BarCodeGenerator(settings);
Image image = generator.GenerateImage();
image.Save("DataMatrix.png", System.Drawing.Imaging.ImageFormat.Png);

要創建矩形的DataMatrix條形碼，請將DataMatrixSymbolShape屬性設置為Rectangle。

settings.DataMatrixSymbolShape = DataMatrixSymbolShape.Rectangle;

完整代碼：

BarcodeSettings settings = new BarcodeSettings();
settings.Type = BarCodeType.DataMatrix;
settings.X = 1.5f;
settings.DataMatrixSymbolShape = DataMatrixSymbolShape.Square;
//rectangular DataMatrix barcode
//settings.DataMatrixSymbolShape = DataMatrixSymbolShape.Rectangle;  
settings.Data = "ABC 123456789ABC 123456789ABC 123456789";
settings.Data2D = "ABC 123456789ABC 123456789ABC 123456789";
BarCodeGenerator generator = new BarCodeGenerator(settings);
Image image = generator.GenerateImage();
image.Save("DataMatrix.png", System.Drawing.Imaging.ImageFormat.Png);
