关于二维指针释放内存的问题

[gougousunny]

这是我在图像处理时的一个程序：
typedef struct DibArray{

BYTE* red;
BYTE* green;
BYTE* blue;
}DibArray;

//申请空间
m_picArray = (DibArray**) new DibArray*[height];
if(!m_picArray)
{
AfxMessageBox("m_picArray分配内存出错！");
delete[] m_picArray;
return false;
}

for(int i=0;i<height;i++)
{
m_picArray[i] = (DibArray*)new DibArray[width];
if(!m_picArray[i])
{
AfxMessageBox("m_picArray[i]分配内存出错！");
delete m_picArray[i];
return false;
}
}

//释放空间

if(m_picArray != NULL)
{
for (int i=0;i<GetHeight();i++)
{
if(m_picArray[i]!=NULL)
{
for (int j=0;j<GetWidth();j++)
{
delete (m_picArray[i][j].blue);
delete (m_picArray[i][j].green);
delete (m_picArray[i][j].red);
}

delete [](m_picArray[i]);
}
}
delete []m_picArray;
}


问题：这样每次内存都不能完全释放，请大虾指教！

[Mr_Ldh]

if(m_picArray != NULL)
{
for (int i=0;i<GetHeight();i++)
{
if(m_picArray[i]!=NULL)
{
delete []m_picArray[i];
}
}
delete []m_picArray;
}

楼上正解

[duckdj]

if(m_picArray != NULL)
{
for (int i=0;i<GetHeight();i++)
{
if(m_picArray[i]!=NULL)
{
for (int j=0;j<GetWidth();j++)
{
delete []m_picArray[i][j];
}

delete [](m_picArray[i]);
}
}
delete []m_picArray;
}
