IDebugComPlusSymbolProvider2:: LoadSymbolsWithCorModule

加载调试给定的符号 ICorDebugModule 对象。

HRESULT LoadSymbolsWithCorModule(
   ULONG32   ulAppDomainID,
   GUID      guidModule,
   ULONGLONG baseAddress,
   IUnknown* pUnkMetadataImport,
   IUnknown* pUnkCorDebugModule,
   BSTR      bstrModuleName,
   BSTR      bstrSymSearchPath
);

int LoadSymbolsWithCorModule(
   uint   ulAppDomainID,
   Guid   guidModule,
   ulong  baseAddress,
   object pUnkMetadataImport,
   object pUnkCorDebugModule,
   string bstrModuleName,
   string bstrSymSearchPath
);

参数

• ulAppDomainID
  [in] 应用程序域的标识符。

• guidModule
  [in] 模块的唯一标识符。

• baseAddress
  [in] 基本内存地址。

• pUnkMetadataImport
  [in] 包含调试符号元数据的对象。

• pUnkCorDebugModule
  [in] 对象实现 ICorDebugModule 接口。

• bstrModuleName
  [in] 模块的名称。

• bstrSymSearchPath
  [in] 搜索路径的符号文件。

返回值

如果成功，则返回; S_OK否则，返回错误代码。

示例

下面的示例演示如何执行显示 IDebugComPlusSymbolProvider2 接口的 CDebugSymbolProvider 对象的方法。

    GUID guidModule,
    ULONGLONG baseOffset,

Error:
