在MAF管道中移动数组非常慢 [英] Moving arrays across MAF pipeline is very slow

问题描述

我有一个项目，我将大型数组从MAF管道移动到插件，这需要很长时间。我只是通过管道传递数组，没有深度复制或迭代。



传递3个291,000个项目的数组，1个数组长，1个数组为double和另一个数组作为枚举，需要3,150ms。获得291,000双打的数组不到1ms。



在主机中

Hi,

I have a project where I'm moving large arrays across a MAF pipeline to an addin and it's taking a very long time. I'm just passing arrays across calls through the pipeline with no deep copying or iterations.

To pass 3 arrays of 291,000 items, 1 array as long, 1 array as double and the other array as enums, takes 3,150ms. Getting an array of 291,000 doubles back takes less than 1ms.

In the Host

addinFunction.SetArrays(array1, array2, array3);

在实际插件中的签名是

in the actual addin the signature is

public void SetArrays(long[] array1, double[] array2, myEnum[] array3);

两个侧面适配器只做类似

both side adapters only do something like

public void SetArrays(long[] array1, double[] array2, myEnum[] array3)
{
     _view.SetArrays(array1, array2, array2);
}

任何人都有任何想法或提示吗？



非常感谢提前。

Anyone have any ideas or hints?

Many thanks in advance.

推荐答案

join array

join array

var z = new int[x.Length + y.Length];
x.CopyTo(z, 0);
y.CopyTo(z, x.Length);

或更改为字节

or change to byte

byte[] firstArray = {2,45,79,33};
byte[] secondArray = {55,4,7,81};
byte[] result = firstArray.Concat(secondArray).ToArray();
