Save file in specific folder

Question

In my Windows forms project, I am trying to save a file generated into a folder called "Invoice". I am able to save to the desktop, but how can it be saved to a subfolder? I know this is very simple fix, but did some research but no luck with the solution.

PdfWriter writer = PdfWriter.GetInstance(doc, 
    new FileStream(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "\\" + ord + ".pdf",
    FileMode.Create));

Answer 1

You can add the name of the folder in the same way that you add the name of the file:

PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "\\Invoice\\" + ord + ".pdf", FileMode.Create));
//                                                                                                                           ^^^^^^^^^^^^

You can also use string.Format to compose the path, like this:

var pathToPdf = string.Format(
    "{0}\\{1}\\{2}.pdf"
,   Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
,   "Invoice"
,   ord
);
PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(pathToPdf, FileMode.Create));

Answer 2

将“ \\\\”替换为“ \\ Invoice \\” + ord +“ .pdf”

Answer 3

If the folder does not exist then you need to create the folder and then write

Use Directory.CreateDirectory

Directory.CreateDirectory Method (String)

Creates all directories and subdirectories as specified by path.

Example:

string fileName = @"C:\Users\SomeUser\My Documents\Foo\Bar\Baz\text1.txt";
Directory.CreateDirectory(Path.GetDirectoryName(fileName));

using (FileStream fs = new FileStream(fileName, FileMode.Create))
{
    // ...
}

once done you can write into the folder like this

PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "\\Invoice\\" + ord + ".pdf", FileMode.Create));

Answer 4

您还可以使用“ 保存文件对话框” ，并将“ 文件流”的第一个参数替换为“保存文件对话框”返回的路径。

I don't like having everything in one line... this is what I'd do

string myFolder = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "MyFolder");
string filePath = Path.Combine(myFolder, ord + ".pdf");
PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(filePath, FileMode.Create));
