Question

Suppose that we declared the line below in our program :

 List<Dictionary<string, string>> list = new List<Dictionary<string, string>>();

so we want to print each member of this list into a file and in the separate page, but all in one document like MyDoc.xps. How can i do to achieve my end ?

EDIT : My difficulty is that how can i create new page in printing process?

Sorry if it duplicates with other questions, i can’t get my answer in site threads. 😐

One way that works is the following:

1. Make the list global class member
2. Use the PrintDocument class under System.Drawing.Printing and use its PrintPage event to set the pages one by one.

Sample code:

private List<Dictionary<string, string>> myList = new List<Dictionary<string, string>>();
private int pageIndex = 0;
private void PrintButton_Click(object sender, EventArgs e)
{
    PrintDocument document = new PrintDocument();
    document.PrintPage += new PrintPageEventHandler(document_PrintPage);
    document.Print();
}

void document_PrintPage(object sender, PrintPageEventArgs e)
{
    if (pageIndex >= myList.Count)
    {
        e.HasMorePages = false;
        return;
    }

    Dictionary<string, string> curData = myList[pageIndex];
    List<string> lines = new List<string>();
    lines.Add("Items count: " + curData.Count);
    curData.Keys.ToList().ForEach(key =>
    {
        lines.Add(string.Format("Key: {0}, Value: {1}", key, curData[key]));
    });
    e.Graphics.DrawString(string.Join("\n", lines), this.Font, SystemBrushes.WindowText, 0, 0);
    pageIndex++;
    e.HasMorePages = pageIndex < myList.Count;
}

On every page printed, the document_PrintPage method will be called. As long as you won’t set e.HasMorePages to false, it will keep printing new pages.

Edit: to force creating .xps file just add those two lines when creating the print document:

document.PrinterSettings.PrintToFile = true;
document.PrinterSettings.PrintFileName = "myfile.xps";
