从C#访问JavaScript数组元素(通过WebBrowser)?

在窗体上使用WebBrowser并使用window.external从Javascript调用C#.传入函数中的Javascript数组类:

var x = [];
x.push(classa);
x.push(classa);

window.external.CSharpFunction(x);

我可以在C#中成功获取x.length:

int length=(int)x.GetType().InvokeMember("length", BindingFlags.GetProperty, null, x, null);

我的问题是如何获得x [0]和x [1]?我试过了

x.GetType().InvokeMember(string.Empty, BindingFlags.GetProperty, null, x, new object[1]{1});
Run Code Online (Sandbox Code Playgroud)

x.GetType().InvokeMember(string.Empty, BindingFlags.InvokeMethod | BindingFlags.Default, null, x, new object[1]{0});

这两个都触发了WebBrowser控件中的错误.

谢谢

允许多个线程访问图像

我正在尝试在C#中进行一些图像处理.我想使用一些线程在我的图像中的几个区域上进行并行计算.线程实际上是在Bitmap对象中获取和设置像素.2个线程绝对没有机会访问同一个像素,所以这不是问题所在.

问题是C#不允许我在同一个Bitmap对象上启动多个线程,即使我确定不会同时读取和修改相同的像素.

有没有办法避免C#引发此错误?或者只是不可能在我的Bitmap对象上运行多个线程?

谢谢,

如果你有GeoTiff,是否可以使用GeoTransform将Lat/Lon点转换为X,Y?

我正在使用GDAL库.目前,我可以接受左上角和右上角,并从原始图像中切出图像.我现在要做的是,接受两个WKT点并转换为X,Y坐标来做同样的事情.我只是想知道如果我知道GeoTransform及它使用的坐标系统(WGS84)是否可以这样做?

如何正确获取 android.net.Uri 的文件大小?

我有一个 android.net.Uri 指向我需要确定文件大小的文件。目前这是使用 contentResolver 上的查询完成的(我使用的是 Xamarin,所以它是 C#):

var cursor = contentResolver.Query(uri, new string[] {
    Android.Provider.OpenableColumns.Size,
    Android.Provider.OpenableColumns.DisplayName 
}, null, null, null);
cursor.MoveToFirst();
size = cursor.GetLong(0);
fileName = cursor.GetString(1);
cursor.Close();

这在大多数情况下都有效,但对于某些文件,该值似乎比正确的文件大小略大(我使用 Total Commander 作为参考)。

尺寸 1 尺寸 2

必须有更好的方法来做到这一点,我真的需要确切的大小信息,并且由于文件非常大,无法先将它们读入内存。为什么我的方法会产生错误的结果?

在此先感谢您的帮助。

如何重新格式化一串C#代码以使其正确缩进?

我发现如果我从网站上复制C#代码并将其粘贴到Notepad ++中,它看起来很难看.基本上它都在一条线上.是否有某个网站,或Notepad ++的加载项,将采取类似1长串的C#代码,然后正确缩进代码?

字典嵌入其他词典的次数是否有实际限制?

我估计我可以这样做:

Dictionary<string, <Dictionary<int, int>> targetChapterAdjustments = new Dictionary<string, <Dictionary<int, int>>();

(创建一个将Dictionary作为其"定义"成员的字典).

但到底能走多远 - 有限制或实际限制吗?

我可以有这样的字典:

Dictionary<string, <Dictionary<int, Dictionary<string, <Dictionary<int, Dictionary<bool, <Dictionary<float, Dictionary<string, <Dictionary<int>>>>>>>>>>>>

...例如?

我会喜欢/讨厌看到这样一个类的创作看起来如何.
