我想在我的ubuntu v16.4 LTS上安装你,但我收到这个错误:

我试图解决这个问题:编写一个函数,找到字符串中最长运行的从零开始的索引.运行是相同字符的连续序列.如果有多个具有相同长度的运行,则返回第一个的索引.

例如,IndexOfLongestRun("abbcccddddcccbba")应该返回6,因为最长的运行是dddd,它首先出现在索引6上.

按照我的所作所为:

private static int IndexOfLongestRun(string str) 
    {
        char[] array1 = str.ToCharArray();
        //Array.Sort(array1);
        Comparer comparer = new Comparer();
        int counter =1;
        int maxCount = 0;
        int idenxOf = 0;

        for (int i =0; i<array1.Length-1 ; i++)
        {
            if (comparer.Compare(array1[i],array1[i+1]) == 0)
            {
                counter++;
            }
            else {
                if(maxCount < counter)
                {
                    maxCount = counter;
                    idenxOf = i - counter + 1;
                }
                counter = 1;
            }
        }
        return idenxOf ;  
    }
}

public class Comparer : IComparer<char>
{
    public int …

我试图使用以下代码将zip文件从asp.net web api返回给客户端:

private byte[] CreateZip(string data)
{
    using (var ms = new MemoryStream())
    {
        using (var ar = new ZipArchive(ms, ZipArchiveMode.Create, true))
        {
            var file = archive.CreateEntry("file.html");

            using (var entryStream = file.Open())
            using (var sw = new StreamWriter(entryStream))
            {
                sw .Write(value);
            }
        }
        return memoryStream.ToArray();
    }
}

public HttpResponseMessage Post([FromBody] string data)
{
    HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK);
    result.Content = new ByteArrayContent(CreateZip(data));
    result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/zip, application/octet-stream");
    return result;
}

当我运行此代码时,我收到以下错误:

ExceptionMessage":"值'application/zip,application/octet-stream'的格式无效."

这是JS代码:

$.ajax({
  type: "POST",
  url: url,
  data: …

我试图拒绝公众使用node express以下代码查看特殊目录中的文件:

app.use(express.static(path.join(__dirname, 'partials')));

app.all('/partials/*', function (req,res, next) {

    res.status(403).send(
    {
        message: 'Access Forbidden'
    });
    next();
});

如果我路由到localhost/partials,我收到消息'Access Forbidden'但不是如果我路由到localhost/partials/files.html

有什么建议？

我试图找出如何创建一个包含不同扩展名的文件的zip存档,例如.txt文件,.html文件

如果我这样做:

using (var zipArchive = new ZipArchive(memory, ZipArchiveMode.Create, true))
{
    var file1= zipArchive .CreateEntry("file1.html");
    var file2= zipArchive .CreateEntry("file2.txt");

    using (var entryStream = file1.Open())
    using (var sw = new StreamWriter(entryStream))
    {
        streamWriter.Write("testing testinsg steing");
    }

    using (var entryStream = file2.Open())
    using (var sw = new StreamWriter(entryStream))
    {
        sw.Write("xyxyxyxyxyxy");
    }
}

创建模式中的条目只能写入一次,并且一次只能打开一个条目.

我怎么解决这个问题？
