VC获取文件大小

方法一: 

WIN32_FIND_DATA fileInfo; 
HANDLE hFind; 
DWORD fileSize; 
const char *fileName = 文件的路径及名字; 
hFind = FindFirstFile(fileName ,&fileInfo); 
if(hFind != INVALID_HANDLE_VALUE) 
fileSize = fileInfo.nFileSizeLow; 
FindClose(hFind); 

方法二：

HANDLE hFile; // the file handle 
DWORD dwFileSize; // temporary storage for file sizes 

// Create the test file. Open it "Create Always" to overwrite any 
// existing file. The data is re-created below. 
hFile = CreateFile(lpcTheFile, GENERIC_READ | GENERIC_WRITE, 0, NULL, 
CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL); 

if (hFile == INVALID_HANDLE_VALUE) { 
printf("hFile is NULL\n"); 
return 4; 
} 
dwFileSize = GetFileSize(hFile, NULL); 
printf("hFile size: %10d\n", dwFileSize);
