将 2 个文本框文本与分隔符组合

Question

SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Text File|*.txt";
sfd.Title = "Save Text File";
if (sfd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
    string path = sfd.FileName;
    string left = string.Format(EmailTxtbx.Text, Environment.NewLine);
    string right = string.Format(PasslTxtbx.Text, Environment.NewLine);
    string[] leftSplit = left.Split(new[] { Environment.NewLine }, StringSplitOptions.None);
    string[] rightSplit = right.Split(new[] { Environment.NewLine }, StringSplitOptions.None);

    string output = "";
    if (leftSplit.Length == rightSplit.Length)
    {
        for (int i = 0; i < leftSplit.Length; i++)
        {
            output += leftSplit[i] + ":" + rightSplit[i] + Environment.NewLine;
        }
    }

    using (StreamWriter bw = new StreamWriter(File.Create(path)))
    {
        textBox1.Text = output;
        bw.Write(output);
        bw.Close();
    }
}

嘿嘿。我有一个问题。假设我有 2 个我想要的文本框在一起：

TextBox1:

测试 41
测试 414
测试 41

TextBox2:

测试55
测试 56
测试 54

TextBox3:

测试41:测试55
Test414:Test56
Test41:Test54

我想将 2 个文件加载到第一个文本框和第二个文本框，并与分隔符（如“：”）结合使用我试过这段代码，但它不起作用。我是 c# 新手。

希望有人能帮助我

I’ll start from scratch. I have 2 textbox. In the first textbok it’s the mails. In the second textbox it’s passwords. What I need to do to combine the textboxes with “:”

试试这个代码片段：

    var txt1 = textBox1.Lines.Where(a => !string.IsNullOrEmpty(a)).ToArray();
    var txt2 = textBox2.Lines.Where(b => !string.IsNullOrEmpty(b)).ToArray();
    var txt3 = "";

    for(int i = 0; i < txt1.Length; i++)
    {
        if (i < txt2.Length)
            txt3 += $"{txt1[i]}:{txt2[2]}{Environment.NewLine}";
        else
            txt3 += $"{txt1[i]}{Environment.NewLine}";
    }

    textBox3.Text = txt3;

祝你好运。
