问题描述
我正在创建一个生成条形码然后打印运送标签的程序。
I am creating a program that generates a bar code and then prints the shipping labels.
我有一个功能,允许用户将电子表格上传到数据网格视图。其中一个列名称是跟踪号码。
I have a function that allows the user to upload a spreadsheet into the datagrid view. One of the column names is "Tracking Number".
我希望能够循环遍历具有跟踪号码的每个单元格,然后将条形码生成新的在一个名为条码的列中的单元格。
I would like to be able to loop through each cell that has a tracking number and then generate a barcode into a a new cell in a column called "barcode".
我知道有一个循环函数,但我从来没有使用过。
I understand there is a loop function for this but I have never used it before.
代码生成条形码如下,它调用两个类:
The code that generates the barcode is the following , it calls two classes:
Image barc = Rendering.MakeBarcodeImage(txtTrack.Text, int.Parse(txtWidth.Text), true);
pictBarcode.Image = barc;
任何帮助将不胜感激。我会很乐意回答任何其他问题。
Any Help would be much appreciated. I will happily answer any other questions.
推荐答案
要遍历每个单元格,可以使用foreach循环
To iterate through every cell, you can use foreach loops
foreach(DataGridViewRow row in yourDataGridView.Rows)
{
foreach(DataGridViewCell cell in row.Cells)
{
//do operations with cell
}
}
