循环与条件问题 [英] Loop with condition issue

问题描述

嗨



尝试用条件创建某种类型的循环。

我需要的是在一定数量的文本时添加了一行，然后移动到新页面，然后继续添加更多，并且每次都能执行相同的操作。



如果尝试了一些循环''，'if'，' foreach'和'for'但是想想我放置它的方式可能是不正确的。



下面的代码运行数据网格上的每一行。这是有效的。

这个foreach应该运行让我们说10次然后新页面直到'N'。 N不能定义数据库总是会改变多少金额。



o这是我发现最适合我打印的方式



thx任何帮助



我尝试过：

Hi

Trying to create some type of loop with a condition.
what i need is when at a certain amount of text lines is added it moves to new page then continue adding more with the ability to do the same every time.

If tried a few loop 'while's, 'if's, 'foreach' and 'for' but think the way i placed it might have been incorrect.

the code below run for every row on a datagrid. this works.
this foreach should run lets say for 10 times then new page untill 'N'. N cant be define how many amount as the database will always change.

o this is a way i found works best for me to print also

thx for any help

What I have tried:

foreach (DataGridViewRow row in dataGridView1.SelectedRows)
                {
                    PartN = row.Cells[0].Value.ToString();
                    SerialN = row.Cells[1].Value.ToString();
                    Descrip = row.Cells[2].Value.ToString();

                    RTBox.SelectionFont = new Font("Courier New", 12);
                    RTBox.AppendText(Descrip);
                    RTBox.SelectionFont = new Font(barcodeName, 26);
                    RTBox.AppendText(Environment.NewLine + PartN);
                    RTBox.SelectionFont = new Font("Courier New", 12);
                    RTBox.AppendText(Environment.NewLine + PartN);
                    RTBox.SelectionFont = new Font("Courier New", 12);
                    if (SerialN == "")
                    {

                    }
                    else
                    {
                        RTBox.AppendText(Environment.NewLine + "S/N: " + SerialN);
                    }

                    RTBox.AppendText(Environment.NewLine + Environment.NewLine);

//RTBox.SelectedRtf = @"{\rtf1 \page}";
                }

推荐答案

您只需要一个定义页面上行数的变量，一个将行计为已处理的行。然后将计数器初始化为0并在每次添加行时计数，例如：

You just need some variable that defines the number of lines on a page, and one that counts the lines as processed.. You then initialise the counter to 0 and count up each time you add a line, something like:

const int maxLines = 66;
int pageNumber = 0;
int lineNumber = 0;
foreach (item that will be processed)
{
    process(theItem);
    lineNumber += 1;
    if (lineNumer == maxLines)
    {
        pageNumber += 1;

        do end of page processing

        lineNumber = 0;
    }
}
