我正在使用 FWTools 和 SharpMap（带有 gdal_sharp）来构建应用程序。我有一个奇怪的错误。加载栅格图层在调试模式下运行良好，但在发布时调用时在构造函数中的 SharpMap.Layers.GdalRasterLayer 中引发异常

 _projectionWkt = _gdalDataset.GetProjectionRef();

完整的例外是：

{System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

奇怪的是，在 Debug 中一切正常。构建设置是准确的，包括 .Net 4.0、x86 平台。

有任何想法吗？

先感谢您

我遇到了类似的问题，但是在使用来自http://www.gisinternals.com/sdk/的当前编译的二进制文件后，问题得到了解决。我在http://vipassanaandenvironmentalinformatics.blogspot.co.nz/2013/03/getting-started-with-c-and-gdal.html记录了对我有用的步骤。

希望这个答案仍然对其他人有所帮助。

这似乎是 Windows 8 的问题，它是 DEP 实现以及 .Net 4.0。我在包装器中使用了 C++ dll，操作系统不允许它执行。它可以通过编辑 DLL 或关闭数据执行保护来解决。
