对'MarshalByRefObject'类型的引用声称它在'mscorlib'中定义，但无法找到它。 [英] Reference to type 'MarshalByRefObject' claims it is defined in 'mscorlib', but it could not be found.

问题描述

我正在使用visual studio 2015开发一个Windows通用应用程序。但是当我尝试在System.drawing.Imaging中使用GetPixel时，我遇到了错误。我找不到解决这个问题的方法。任何人遇到同样的问题并有解决方案吗？

提前致谢！

彩色图像; 
  float  [，] imagegray =  new   float  [image.Width，image.Height]; 
  for （ int  i =  0 ; i <  image.Width; i ++）
 {
  for  （ int  j =  0 ; j <  image.Height; j ++）
 {
 imagecolor = image.GetPixel（i，j）; 
 imagegray [i，j] =  0  .299f * imagecolor.R +  0  .587f * imagecolor.G +  0  .114f * imagecolor.B; 
} 
} 
 

解决方案

您需要浏览并添加.NET程序集的参考吗？



这是在System.Drawing

I'm working on a windows universal app with visual studio 2015. But I meet the error when I tried to use GetPixel in System.drawing.Imaging. I can't find the solution for this problem. Anyone has met the same problem and have a solution?
Thanks in advance!

Color imagecolor;
float[,] imagegray = new float[image.Width, image.Height];
for (int i = 0; i < image.Width; i++)
{
    for (int j = 0; j < image.Height; j++)
    {
        imagecolor = image.GetPixel(i, j);
        imagegray[i, j] = 0.299f * imagecolor.R + 0.587f * imagecolor.G + 0.114f * imagecolor.B;
    }
}

解决方案

You need to browse and add refrence from .NET assemblies?

It is in System.Drawing

Refer :
