如何把文本文件中横排文字变为竖排

[Jiehash]

如题

例如：文本文件中显示为：a b c d
d e k l

变为：
a d
b e
c k
d l

然后写入到一个文本文件中。

        string str = string.Empty;
        string a = "abcddekl";
        char[] arr = a.ToCharArray();

        for (int i = 0; i < arr.Length / 2; i++)
        {
            str += arr[i].ToString() +arr[i + arr.Length / 2].ToString() + "<br/>";
        }
        Response.Write(str);
         
        //这只是个思路，你自己写的时候要考虑，arr数组是否能被整除等

[Quote=引用 1 楼 porschev 的回复:]
C# code

string str = string.Empty;
string a = "abcddekl";
char[] arr = a.ToCharArray();

for (int i = 0; i < arr.Length / 2; i++)
{
str += ……

他的里面有些空格啊，不好处理。

用流的方式不知道能否处理。

若楼主的字符无规律该怎么办呢？

private void button1_Click(object sender, EventArgs e)
{
    string path = string.Format("{0}\\aaa.txt",Application.StartupPath);
    StreamReader sr = new StreamReader(new FileStream(path, FileMode.Open));
    string read = sr.ReadToEnd();
    sr.Close();
    string[] split = read.Split(new char[] { '\r','\n' }, StringSplitOptions.RemoveEmptyEntries);
    string[] result = ConvertToVerticalText(split);

    path = string.Format("{0}\\result.txt",Application.StartupPath);
    StreamWriter sw = new StreamWriter(new FileStream(path, FileMode.CreateNew));
    foreach (string s in result)
    {
        sw.WriteLine(s);
    }
    sw.Close();
}

string[] ConvertToVerticalText(string[] input)
{
    int max = 0;
    for (int i = 0; i < input.Length; i++)
    {
        max = input[i].Length > max ? input[i].Length : max;
    }
    string[] result = new string[max];
    for (int i = 0; i < input.Length; i++)
    {
        for (int inputIndex = 0; inputIndex < max; inputIndex++)
        {
            if (inputIndex < input[i].Length)
                result[inputIndex] += input[i][inputIndex];
            else
                result[inputIndex] += " ";
        }
    }
    return result;
}

input file:
123456
abcde
ghija
aac
bbb
result file:
1agab
2bhab
3cicb
4dj  
5ea  
6
