Path.Combine很方便,但是.NET框架中是否有类似的URL函数?

我正在寻找这样的语法:

Url.Combine("http://MyUrl.com/", "/Images/Image.jpg")

这将返回:

"http://MyUrl.com/Images/Image.jpg"

我使用此代码来解决问题:

string[] brokenBaseUrl = Context.Url.TrimEnd('/').Split('/');
string[] brokenRootFolderPath = RootFolderPath.Split('/');

for (int x = 0; x < brokenRootFolderPath.Length; x++)
{
    //if url doesn't already contain member, append it to the end of the string with / in front
    if (!brokenBaseUrl.Contains(brokenRootFolderPath[x]))
    {
        if (x == 0)
        {
            RootLocationUrl = Context.Url.TrimEnd('/');
        }
        else
        {
            RootLocationUrl += String.Format("/{0}", brokenRootFolderPath[x]);
        }
    }
}

使用此项:

public static class WebPath
{
    public static string Combine(params string[] args)
    {
        var prefixAdjusted = args.Select(x => x.StartsWith("/") && !x.StartsWith("http") ? x.Substring(1) : x);
        return string.Join("/", prefixAdjusted);
    }
}
Path.Combine("Http://MyUrl.com/", "/Images/Image.jpg").Replace("\\", "/")

我使用此代码来解决问题:

string[] brokenBaseUrl = Context.Url.TrimEnd('/').Split('/');
string[] brokenRootFolderPath = RootFolderPath.Split('/');

for (int x = 0; x < brokenRootFolderPath.Length; x++)
{
    //if url doesn't already contain member, append it to the end of the string with / in front
    if (!brokenBaseUrl.Contains(brokenRootFolderPath[x]))
    {
        if (x == 0)
        {
            RootLocationUrl = Context.Url.TrimEnd('/');
        }
        else
        {
            RootLocationUrl += String.Format("/{0}", brokenRootFolderPath[x]);
        }
    }
}

我必须指出,Path.Combine似乎也能直接实现这一点,至少在.NET 4上是如此。

我发现Uri构造函数将“\”转换为“/”。因此,您也可以将Path.Combine与Uri构造函数一起使用。

 Uri baseUri = new Uri("http://MyUrl.com");
 string path = Path.Combine("Images", "Image.jpg");
 Uri myUri = new Uri(baseUri, path);
