C#使用BerkeleyDB操作简介[7]

if (keyBufferLength < keySize)

{

keyStreamSetLength(keySize);

key = DbEntryOut(keyStreamGetBuffer());

}

if (dataBufferLength < dataSize)

{

dataStreamSetLength(dataSize);

data = DbEntryOut(dataStreamGetBuffer());

}

continue;

case ReadStatusSuccess:

dataStreamPosition = ;

dataStreamSetLength(dataSize);

cust = (IPut)formatterDeserialize(dataStream);

return true;

default:

return false;

}

} while (true);

}

}

调用方法

首先要有一个写入的实体类必须可以序列化并且实现IPut接口

[Serializable()]

class Item : IPut

{

public string Name { get; set; }

public string Text { get; set; }

public int ID { get; set; }

public override string ToString()

{

return stringFormat(ID:{} Key:{} ID Name);

}

public string Key

{

get { return Name; }

}

}

操作

using (BDBManager manager = new BDBManager(db dbdat))

{

bool success = managerSet(new Item() { ID = Name = TestText = });

ConsoleWriteLine(stringFormat(set is {} success));

}

using (BDBManager manager = new BDBManager(db dbdat))

{

IPut put = new Item() { Name = Test };

bool success = managerGet(ref put);

ConsoleWriteLine(stringFormat(read is {}item : {} success putToString()));

}

using (BDBManager manager = new BDBManager(db dbdat))

{

IPut put = new Item() { Name = Test };

bool success = managerRemove(put);

ConsoleWriteLine(stringFormat(remove is {}item : {} success putToString()));

}

using (BDBManager manager = new BDBManager(db dbdat))

{

List<IPut> list = managerFind();

foreach (var item in list)

{

ConsoleWriteLine(itemToString());

}

}

ConsoleWriteLine(end);

ConsoleReadKey();
