引用从Visual Studio文本编辑器传递的IntPtr在AddIN中引发异常

问题描述

您好，

EnvDTE.

Hi,
    

EnvDTE.

表达 getPixelsAsPointer = applicationObject.Debugger.GetExpression( "pixelIntPtr" ， true ，5);
pixelIntPtr是引用字节数组的IntPtr.

IntPtr通过以下方式

Expression getPixelsAsPointer = applicationObject.Debugger.GetExpression("pixelIntPtr", true,5);
pixelIntPtr is a IntPtr refering to a byte array.

I will get the IntPtr by the following way

 

IntPtr pixPointer =( IntPtr ) 转换 .ToInt32 (getPixelsAsPointer.Value);

IntPtr pixPointer = (IntPtr)Convert.ToInt32(getPixelsAsPointer.Value);

 

不安全

{

byte * ptr =(byte *)pixPointer.ToPointer(); //在这里获取异常

byte* ptr=(byte*)pixPointer.ToPointer(); //Getting Exception Here

for(int iIndex = 0; iIndex< height; iIndex ++)
{

for (int iIndex = 0; iIndex < height; iIndex++)
{

pixData [iIndex] = * ptr;

 pixData[iIndex] =*ptr;

ptr = ptr + 1;

 ptr = ptr + 1;

}}

}

我尝试遍历字节数组时遇到异常:AccessViolationException
尝试读取或写入受保护的内存.这通常表明其他内存已损坏.

我还想知道AddIn和Visual Studio文本编辑器是否处于同一进程中?
以及如何在AddIn中使用IntPtr?
请让我知道如何解决此问题.

}

Whetn i try to iterate through the byte array i am getting Exception:AccessViolationException
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

And i also want to know whether the AddIn and Visual Studio Text Editor are in same process?
And how to use IntPtr in AddIn?
Please let me know how to solve this issue.
