1.文件的读取和写入 UFUNCTION(BlueprintCallable, Category File)static bool loadStringFromFile(FString filePath, FString resultString);UFUNCTION(BlueprintCallable, Category File)static bool writeStringToFile(TArrayFString saveFile, FString filePath);
bool UMyBlueprintFunctionLibrary::loadStringFromFile(FString filePath, FString resultString)
{if (!filePath.IsEmpty()){if (FFileHelper::LoadFileToString(resultString, *filePath)){return true;}else{//error}}return false;
}bool UMyBlueprintFunctionLibrary::writeStringToFile(TArrayFString saveFile, FString filePath)
{if (!filePath.IsEmpty()){if (FFileHelper::SaveStringArrayToFile(saveFile, *filePath)){return true;}else{//error}}return false;
}
2.获取文件名、后缀名、文件名 UFUNCTION(BlueprintCallable, Category File)static FString GetFilePath(FString path);UFUNCTION(BlueprintCallable, Category File)static FString GetFileName(FString InPath,bool bRemovePath);UFUNCTION(BlueprintCallable, Category File)static FString GetFileExtension(FString InPath, bool bInCludeDot);
FString UMyBlueprintFunctionLibrary::GetFilePath(FString path)
{FString result;result FPaths::GetPath(*path);return result;
}FString UMyBlueprintFunctionLibrary::GetFileName(FString InPath, bool bRemovePath)
{return FPaths::GetBaseFilename(*InPath,bRemovePath);
}FString UMyBlueprintFunctionLibrary::GetFileExtension(FString InPath, bool bInCludeDot)
{return FPaths::GetExtension(*InPath,bInCludeDot);
}
3.创建文件夹和删除文件夹 UFUNCTION(BlueprintCallable, Category File)static void CreateFolder(FString FolderName);UFUNCTION(BlueprintCallable, Category File)static void DeleteFolder(FString FolderName); 在cpp中引入FileManagerGeneric.h
#include Runtime/Core/Public/HAL/FileManagerGeneric.h
void UMyBlueprintFunctionLibrary::CreateFolder(FString FolderName)
{//FString path FPaths::ProjectContentDir();FPlatformFileManager::Get().GetPlatformFile().CreateDirectoryTree(*FolderName);
}void UMyBlueprintFunctionLibrary::DeleteFolder(FString FolderName)
{//FString path FPaths::ProjectContentDir();FPlatformFileManager::Get().GetPlatformFile().DeleteDirectoryRecursively(*FolderName);
}
4.文件的移动和查找 UFUNCTION(BlueprintCallable, Category File)static bool MoveFileTo(FString To, FString From);UFUNCTION(BlueprintCallable, Category File)static TArrayFString FindFileFolder(FString Path, FString Filter, bool Files, bool Directory);
bool UMyBlueprintFunctionLibrary::MoveFileTo(FString To, FString From)
{return IFileManager::Get().Move(*To,*From);
}TArrayFString UMyBlueprintFunctionLibrary::FindFileFolder(FString Path, FString Filter, bool Files, bool Directory)
{TArrayFString FilePathList;FilePathList.Empty();FFileManagerGeneric::Get().FindFilesRecursive(FilePathList, *Path, *Filter, Files, Directory);return FilePathList;
}
