把一个DataTable类转换成Byte数组可以这样
DataTable LeafDataTableTemp;
byte[] LeafDataTableByteTemp;
System.IO.MemoryStream LeafMemoryStreamTemp = new MemoryStream();
BinaryFormatter LeafBinaryFormatterTemp = new BinaryFormatter();
LeafBinaryFormatterTemp.Serialize(LeafMemoryStreamTemp, LeafDataTableTemp);
LeafDataTableByteTemp = LeafMemoryStreamTemp.GetBuffer();
然后从Byte数组转换回DataTable类可以这样
byte[] LeafDataTableByteTemp;
DataTable LeafData;
BinaryFormatter LeafBinaryFormatterTemp = new BinaryFormatter();
LeafData = (DataTable)LeafBinaryFormatterTemp.Deserialize(new MemoryStream(LeafDataTableByteTemp));
那么假如我自定义一个类
class LeafClassDataPack
public string a;
public int b;
public byte[] c;
我如何把这个类转换成二进制数据byte[]
又如何从二进制数据byte[]转换回这个类呢
你的方法是没问题的，goorcome说得对，只能序列化实例。另外你的类声明没有说明可序列化。
[Serializable()]
class LeafClassDataPack
public string a;
public int b;
public byte[] c;
下面是测试代码：
private void button3_Click(object sender, EventArgs e)
LeafClassDataPack lcdp= DeserializeMyClass(SerializeMyClass());
Text = lcdp.a;
private byte[] SerializeMyClass()
LeafClassDataPack leafClassDataPack=new LeafClassDataPack();
leafClassDataPack.a = "test";
byte[] leafMyClassByteTemp;
MemoryStream leafMemoryStreamTemp = new MemoryStream();
BinaryFormatter leafBinaryFormatterTemp = new BinaryFormatter();
leafBinaryFormatterTemp.Serialize(leafMemoryStreamTemp, leafClassDataPack);
leafMyClassByteTemp = leafMemoryStreamTemp.GetBuffer();
return leafMyClassByteTemp;
private LeafClassDataPack DeserializeMyClass(byte[] leafMyClassByteTemp)
LeafClassDataPack leafClassDataPack;
BinaryFormatter leafBinaryFormatterTemp = new BinaryFormatter();
leafClassDataPack = (LeafClassDataPack)leafBinaryFormatterTemp.Deserialize(new MemoryStream(leafMyClassByteTemp));
return leafClassDataPack;
参考技术A 觉得只能转换数据，实例什么得，不能转换类本身吧
