Podstawowa inicjalizacja i konfiguracja

GroupDocs.Conversion is the core class that orchestrates file transformations. After adding the package, you instantiate a Converter object with the source file path and optional configuration.

Initialize the converter Converter is the primary class used to load a document and perform conversions.

using System;
using GroupDocs.Conversion;

// Initialize the converter with the source DGN file path
var documentPath = "YOUR_DOCUMENT_DIRECTORY\sample.dgn";
using (var converter = new Converter(documentPath))
{
    // Conversion logic will go here
}

With our setup complete, let’s implement the conversion process.

Jak skonwertować DGN do Excela w C#?

The conversion workflow consists of loading the DGN file, configuring spreadsheet options, and invoking the Convert method. By using the Converter class together with SpreadsheetConvertOptions, you can control sheet names, include metadata, and limit pages, ensuring efficient and accurate Excel output for any size drawing.

Załaduj źródłowy plik DGN

First, define the absolute or relative paths for the input DGN and the output XLSX.

Krok 1: Zdefiniuj ścieżki plików

string documentPath = System.IO.Path.Combine("YOUR_DOCUMENT_DIRECTORY", "sample.dgn");
string outputFolder = System.IO.Path.Combine("YOUR_OUTPUT_DIRECTORY", "output");
string outputFile = System.IO.Path.Combine(outputFolder, "dgn-converted-to.xlsx");

// Ensure the output directory exists
if (!System.IO.Directory.Exists(outputFolder))
{
    System.IO.Directory.CreateDirectory(outputFolder);
}

Krok 2: Załaduj plik DGN

using (var converter = new Converter(documentPath))
{
    // Conversion process will be defined here
}

Skonfiguruj opcje konwersji

ConversionException is thrown when the conversion process encounters an error. SpreadsheetConvertOptions defines settings for Excel output such as sheet naming, metadata inclusion, and page range.

// Specify that we're converting to an Excel spreadsheet format
var options = new SpreadsheetConvertOptions();

Wykonaj konwersję

Finally, execute the conversion and write the result to disk.

Krok 4: Wykonaj i zapisz konwersję

converter.Convert(outputFile, options);

Wskazówki rozwiązywania problemów

  • Permissions – Verify the process has read/write access to the folders.
  • Error Handling – Wrap the conversion call in a try‑catch block to capture ConversionException and log details.

Typowe problemy i rozwiązania

ProblemRozwiązanie
“File not found” errorUse Path.GetFullPath to resolve relative paths and ensure the file exists.
Memory spikes on large DGNsProcess the file in chunks by setting ConverterOptions.PageRange to limit pages per conversion.
