Hi,

I have 2 text files and compare them. If there is a line in file1 is different than a line in file 2, it will write those line in textboxes with red.

When i wrote the code below, it show all text in red. How can i change them?

string MOFile = "MOOutputTextFile.txt";
           
            string line1, line2;
            var file1 = File.OpenText(WSFile);
            var file2 = File.OpenText(MOFile);

            int counter = 0;
            try
            {
                if((File.Exists(WSFile)) && (File.Exists(MOFile)))
                {
                    while (((line1 = file1.ReadLine()) != null) && (line2 = file2.ReadLine()) != null)
                    {
                        textBox1.Text += line1 + "\r\n";
                        textBox2.Text += line2 + "\r\n";
                        if (!line1.Equals(line2))
                        {
                            textBox1.Text += line1 + "\r\n";
                            textBox2.Text += line2 + "\r\n";
                            textBox1.ForeColor = Color.Red;
                           
                        }
                        counter++;
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
    }

推荐答案

您可以保守秘密吗?然后听:字符串没有颜色.

您是否注意到textBox1.ForeColor = Color.Red;?这没有任何意义.您只需一次又一次地以相同的颜色不断绘制相同的控件，并具有非凡的毅力，值得更好的应用.

怎么改变呢?通过停下来做.您只需分配属性ForColor一次.还有更多颜色，您知道吗?

Can you keep a secret? Then listen: strings don''t have color.

Did you noticed textBox1.ForeColor = Color.Red;? It does not make any sense. You just keep painting the same control with the same color in cycle, again and again, with remarkable perseverance which deserves better application.

How to change it? By stopping to do it. You need to assign the property ForColor only once. And there are more colors, did you know?

从此处开始:

A textbox is the wrong control for the behavior you have described.
