main文件中大家直接调用testReading函数就可以了
```cpp
void testReading(char* file) {
// Load DXF file into memory:
std::cout << "Reading file " << file << "...\n";
Test_CreationClass* creationClass = new Test_CreationClass();
DL_Dxf* dxf = new DL_Dxf();
if (!dxf->in(file, creationClass)) { // if file open failed
std::cerr << file << " could not be opened.\n";
return;
}
delete dxf;
delete creationClass;
}
```
大家运行一下代码应该可以得到dxf文件的数据，运行结果如下：
需要注意的是，如果大家的工程和build文件夹不在一起的话，可能会提示你.dxf文件找不到，你需要把等待读取的.dxf文件放到build文件夹中。
