从 CSV 读取数据到屏幕输出 [英] Reading Data from CSV to Screen output

问题描述

这可能不允许，但我还是会问.

This may not be allowed but I'll ask anyway.

我正在尝试开发一种类似于 YALV 的产品，但用于自定义日志.

I'm trying to develop a product similar to YALV but for a custom logs.

我有一个 CSV 文件，我想读取它并在屏幕上显示在一个表格中，该表格可以像 YALV 一样滚动、过滤、着色等.

I have a CSV file that I want to read in and display on screen in a table that can be scrolled, filtered, coloured, etc similarly to YALV.

我有用于读取和解密 CSV 并以整洁的格式输出到另一个文件的代码.我想对其进行调整以使其出现在屏幕上.

I have code for reading and deciphering the CSV and outputting in a neat format to another file. I want to adapt this to get it to screen.

我有 C# 和 C 方面的经验，但只与控制台相关.有人可以指导我在正确的方向上至少以与 YALV 类似的格式在窗口中读取文件吗?我可能的步骤是什么?我不确定从哪里开始......

I have experience in C# and C but only console related. Could someone guide me int he right direction to at least get the file being read in a Window in a similar format to YALV? What would be my possible steps? I'm unsure where to start....

谢谢
