PDF Services API: Merge issue

While combine/merging pdf files to single file it’s not merging in sequence, we are sending file list in sequence but however it’s not merging in sequence. Kindly let us know is there any option to merge the files in sequence.

 

Example,

10 individual pdf files (file1.pdf, file2.pdf, file3.pdf, file4.pdf…file10.pdf) needs to merge to single file (File.pdf). When we use PDF Services API, it’s not merging in correct order. File.Pdf should have form file1,file2,file3,file4…file10 in this order. But File.pdf it’s not in sequence it’s like file1,file3,file7,file3,etc. We need to single file as in order instead of out of sequence.

//inputPath is Path (C:\test\AllPDFFiles\)

public static void mergePDFMethod(Credentials credentials, string inputPath, string outputPath)
{

try
{
//Create an ExecutionContext using credentials and create a new operation instance.
ExecutionContext executionContext = ExecutionContext.Create(credentials);
CombineFilesOperation combineFilesOperation = CombineFilesOperation.CreateNew();

// Add operation input from source files.

filesList = Directory.GetFiles(Path.GetDirectoryName(Path.GetDirectoryName(@outputPath) + "\\TempMerge\\"), "*.pdf", SearchOption.TopDirectoryOnly).Select(fn => new FileInfo(fn)).OrderBy(f => f.Name).ToArray();
foreach (var a in filesList.ToArray())
{
FileRef combineSource = FileRef.CreateFromLocalFile(a.ToString());
combineFilesOperation.AddInput(combineSource);

}
FileRef result = combineFilesOperation.Execute(executionContext);

// Save the result to the specified location.
result.SaveAs(@outputPath);
Console.WriteLine("End of Merge method");
}

catch (Exception ex)
{
Console.WriteLine(ex.Message);
Console.WriteLine(ex.StackTrace);
}
Console.WriteLine("End of catch");
}

Poseted code which we are using in C#

//inputPath is Path (C:\test\AllPDFFiles\)

public static void mergePDFMethod(Credentials credentials, string inputPath, string outputPath)
{

try
{
//Create an ExecutionContext using credentials and create a new operation instance.
ExecutionContext executionContext = ExecutionContext.Create(credentials);
CombineFilesOperation combineFilesOperation = CombineFilesOperation.CreateNew();

// Add operation input from source files.

filesList = Directory.GetFiles(Path.GetDirectoryName(Path.GetDirectoryName(@outputPath) + "\\TempMerge\\"), "*.pdf", SearchOption.TopDirectoryOnly).Select(fn => new FileInfo(fn)).OrderBy(f => f.Name).ToArray();
foreach (var a in filesList.ToArray())
{
FileRef combineSource = FileRef.CreateFromLocalFile(a.ToString());
combineFilesOperation.AddInput(combineSource);

}
FileRef result = combineFilesOperation.Execute(executionContext);

// Save the result to the specified location.
result.SaveAs(@outputPath);
Console.WriteLine("End of Merge method");
}

catch (Exception ex)
{
Console.WriteLine(ex.Message);
Console.WriteLine(ex.StackTrace);
}
Console.WriteLine("End of catch");
}
