在512字符块分割字符串 [英] Split string in 512 char chunks

问题描述

也许一个基本的问题，但让我们说我有一个字符串，它是2000个字符长，我需要拆分此字符串到每个最多512字符块。

Maybe a basic question but let us say I have a string that is 2000 characters long, I need to split this string into max 512 character chunks each.

时有一个很好的方式，就像一个循环或因此这样做

Is there a nice way, like a loop or so for doing this?

推荐答案

事情是这样的：

private IList<string> SplitIntoChunks(string text, int chunkSize)
{
    List<string> chunks = new List<string>();
    int offset = 0;
    while (offset < text.Length)
    {
        int size = Math.Min(chunkSize, text.Length - offset);
        chunks.Add(text.Substring(offset, size));
        offset += size;
    }
    return chunks;
}

或只是遍历：

private IEnumerable<string> SplitIntoChunks(string text, int chunkSize)
{
    int offset = 0;
    while (offset < text.Length)
    {
        int size = Math.Min(chunkSize, text.Length - offset);
        yield return text.Substring(offset, size);
        offset += size;
    }
}

请注意，这个分裂成UTF-16代码块单位，这是不一样分裂成的Unicode码分块，而这又可能不一样分裂成字形的块相当的相同。

Note that this splits into chunks of UTF-16 code units, which isn't quite the same as splitting into chunks of Unicode code points, which in turn may not be the same as splitting into chunks of glyphs.
