C＃換行打印出一個字符串

Question

我如何打印出整個字符串？ 我想知道如何進行換行打印此字符串？

謝謝你的回答

    private void drucken_Click(object sender, EventArgs e)
    {

        PrintDialog printDialog = new PrintDialog();
        PrintDocument printDocument = new PrintDocument();
        printDialog.Document = printDocument;

        printDocument.PrintPage += new PrintPageEventHandler (PrintReceiptPage);

        DialogResult result = printDialog.ShowDialog();

        if (result == DialogResult.OK)
        {
            printDocument.Print();
        }           
    }

    private void PrintReceiptPage(object sender, PrintPageEventArgs e)
    {
        string message = "Haalloodhsak dfsdfsfdsfsdfdssdddddddddddddddsf  Tetsn dfgdfgdfgdfg dfgdfgdfgdfg dfgdfgdfgdfggdfdfg gdgdgdffgddfgdfgdfggdf dfgdfgdfgdfggdf";
        int y;
        // Print receipt
        Font myFont = new Font("Times New Roman", 15, FontStyle.Bold);
         y = e.MarginBounds.Y;
       e.Graphics.DrawString(message , myFont, Brushes.Red,   e.MarginBounds.X, y);
    }

將您的PrintReceiptPage方法更改為如下所示：

private void PrintReceiptPage(object sender, PrintPageEventArgs e)
{
    string message = "Haalloodhsak dfsdfsfdsfsdfdssdddddddddddddddsf  Tetsn dfgdfgdfgdfg dfgdfgdfgdfg dfgdfgdfgdfggdfdfg gdgdgdffgddfgdfgdfggdf dfgdfgdfgdfggdf";
    int yMargin;
    // Print receipt
    Font myFont = new Font("Times New Roman", 15, FontStyle.Bold);
    yMargin = e.MarginBounds.Y;

    // Create rectangle for drawing. 
    float x = 150.0F;
    float y = 150.0F;
    float width = 200.0F;
    float height = 50.0F;
    RectangleF drawRect = new RectangleF(x, yMargin, width, height);

    e.Graphics.DrawString(message, myFont, Brushes.Red, drawRect);
}

我認為沒有任何方法可以自動包裝文本。 您可以做的一件事是測量字符串的一部分，如果有足夠的空間，則添加字符。 如果沒有足夠的空間，請打印並向下移動一點。

要測量字符串，請使用e.Graphics.MeasureString(string,Font) 。 希望這可以幫助。
