Merge and Split

The PDF Creator offers an API for merging PDF documents or extracting pages from a PDF document using MergePdf and SplitPdf classes.

Code Sample

The code sample below is taken from MergeSplitDemo sample application:

protected void btnCreatePDF_Click(object sender, EventArgs e)
    string workingFolderPath = System.IO.Path.Combine(Server.MapPath("~"), "Files");

    string firstFilePath = System.IO.Path.Combine(workingFolderPath, "oss.pdf");
    string secondFilePath = System.IO.Path.Combine(workingFolderPath, "google.pdf");
    string mergedFilePath = System.IO.Path.Combine(workingFolderPath, "MergeFileResult.pdf");
    string extractedFilePath = System.IO.Path.Combine(workingFolderPath, "SplitFileResult.pdf");

    // merge files into disk file
    string[] filesToMerge = new string[2];
    filesToMerge[0] = firstFilePath;
    filesToMerge[1] = secondFilePath;
    // merge the two files into mergedFilePath on disk
    MergePdf.Merge(filesToMerge, mergedFilePath);

    // extract first page from the merged document and create a PDF file with it
    SplitPdf.ExtractPages(mergedFilePath, 0, 1, extractedFilePath);

    //merge streams
    System.IO.FileStream fs1 = new System.IO.FileStream(firstFilePath, System.IO.FileMode.Open, System.IO.FileAccess.Read);
    System.IO.FileStream fs2 = new System.IO.FileStream(secondFilePath, System.IO.FileMode.Open, System.IO.FileAccess.Read);

    System.IO.Stream[] streamsToMerge = new System.IO.Stream[2];
    streamsToMerge[0] = fs1;
    streamsToMerge[1] = fs2;

    // prepare Response
    Response.Buffer = true;
    Response.AddHeader("content-disposition", "attachment; filename=MergeStreamsResult.pdf");
    Response.AddHeader("content-type", "application/pdf" );

    //Save the merge result directly on the Response stream to browser
    MergePdf.Merge(streamsToMerge, Response.OutputStream);

    //send buffered output to client browser

    // close the source streams
