我对通用集合没有经验。我需要对 TDictionary 进行排序。
type TSearchResult = TPair<Integer,double>;
var
target_results : TDictionary<Integer, double>;
session_search_results : array[0..max_searches] of TArray<TSearchResult>;
我正在使用此代码进行排序
session_search_results[session_search_id]:= target_results.ToArray;
TArray.Sort<TSearchResult>(session_search_results[session_search_id],
TComparer<TSearchResult>.Construct(
function(const L, R: TSearchResult): Integer
begin
Result := Round(R.Value - L.Value);
end
));
为什么我会因此遇到访问冲突?我究竟做错了什么?
补充:
如果我遍历数组
for i:= 0 to Length(session_search_results[session_search_id])-1 do
MyDebug(IntToStr(session_search_results[session_search_id][i].Key)+' = value = '
+ FloatToStr(session_search_results[session_search_id][i].Value));
我得到以下输出:
Debug Output: ==>CoreSearchText: array length=8<== Process TestApp.exe (2536)
Debug Output: ==>100007 = value = 19,515<== Process TestApp.exe (2536)
Debug Output: ==>100003 = value = 2,4<== Process TestApp.exe (2536)
Debug Output: ==>100005 = value = 12<== Process TestApp.exe (2536)
Debug Output: ==>100008 = value = 2,4<== Process TestApp.exe (2536)
Debug Output: ==>100002 = value = 2,4<== Process TestApp.exe (2536)
Debug Output: ==>100004 = value = 2,4<== Process TestApp.exe (2536)
Debug Output: ==>100009 = value = 40,515<== Process TestApp.exe (2536)
Debug Output: ==>100001 = value = 15<== Process TestApp.exe (2536)
应用排序时,访问冲突会使应用程序崩溃。阵列似乎没问题。可能是什么原因?谢谢!
