Merge document word in order that i want with spire.doc

Question

i'm trying to merge multiple word document into one document using spire.doc, but I would like the order to be my choice.

Document doc = new Document();

//document1
doc.LoadFromFile(sourcefile1, FileFormat.Docx);
doc.InsertTextFromFile(@"C:\document.docx", FileFormat.Docx);
doc.SaveToFile(@"C:\document.docx", FileFormat.Docx);

//document2
doc.LoadFromFile(sourcefile2, FileFormat.Docx);
doc.InsertTextFromFile(@"C:\document.docx", FileFormat.Docx);
doc.SaveToFile(@"C:\document.docx", FileFormat.Docx);

//document 3
doc.LoadFromFile(sourcefile3, FileFormat.Docx);
doc.InsertTextFromFile(@"C:\document.docx", FileFormat.Docx);
doc.SaveToFile(@"C:\document.docx", FileFormat.Docx);

For example I would like document1 to be on the front page but currently it is put on the last page.

Thank you all

You can use the following code to achieve your requirement:

Document doc = new Document();
doc.LoadFromFile("file1.docx");

string[] files = new string[] {"file2.docx", "file3.docx" };

//Insert contents from multiple files into file1.docx
foreach (string file in files)
{
    doc.InsertTextFromFile(file, FileFormat.Docx);
}

//Save the result file
doc.SaveToFile("merge.docx", FileFormat.Docx);
