我正在尝试根据Vala documentation将文件移动到另一个目录,但是以下方法无效。
请告诉我是否误解了move方法的工作原理。
grouped.sum(['quantity'])
端子输出(无错误,dest中没有test.txt):
public void moveMyFile(){
GLib.File dest = GLib.File.new_for_path("~/Desktop/dest/");
GLib.File src = GLib.File.new_for_path("~/Desktop/src/test.txt");
print("\ndest path : %s \n", dest.get_path());
print("src path : %s \n", src.get_path());
if(dest.query_exists() && src.query_exists()){
try {
src.move(dest, FileCopyFlags.NONE, null);
} catch (Error e) {
print ("moveMyFile Error: %s\n", e.message);
}
}
}
dest path : /home/srdr/Serdar/Workspaces/WorkspaceBudgie/budgie-projects/budgie-trash/build/~/Desktop/dest
src path : /home/srdr/Serdar/Workspaces/WorkspaceBudgie/budgie-projects/budgie-trash/build/~/Desktop/src/test.txt

答案 0 :(得分:2)
我正在检查dest文件是否存在。我从if语句中删除了dest.query_exists()。现在可以了。
