//测试4：深度复制 TextBox
try
{
Console.WriteLine("=== 深度复制 TextBox ===");
txtTest.Text = "1234";
Console.WriteLine("复制前：" + txtTest.Text);
TextBox txtTmp = new TextBox();
txtTmp = (TextBox)DataManHelper.DeepCopyObject(txtTest);
Console.WriteLine("复制后：" + txtTmp.Text);
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
//测试5：深度复制 DataGridView
try
{
Console.WriteLine("=== 深度复制 DataGridView ===");
DataGridView dgvTmp = new DataGridView();
dgvTmp = (DataGridView)DataManHelper.DeepCopyObject(dgvTest);
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}
其中txtTest是一个测试用的TextBox，dgvTmp是一个测试用的DataGridView，TestClass是一个自定义类，TestClassWithS是添加了Serializable特性的TestClass类，它们的具体实现如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace DataCopyTest
{
public class TestClass
{
public int a;
public string b;
public string[] c;
public TestClass d;
public override string ToString()
{
string s = "a:" + a + "n";
if (b != null)
{
s += "b:" + b + "n";
}
if (c != null)
{
foreach (string tmps in c)
{
if (!string.IsNullOrWhiteSpace(tmps))
{
s += "c:" + tmps + "n";
}
}
}
if (d != null)
{
s += d.ToString();
}
return s;
}
}
//支持序列化的TestClass
[Serializable]
public class TestClassWithS
{
public int a;
public string b;
public string[] c;
public TestClassWithS d;
public override string ToString()
{
string s = "a:" + a + "n";
if (b != null)
{
s += "b:" + b + "n";
}
if (c != null)
{
foreach (string tmps in c)
{
if (!string.IsNullOrWhiteSpace(tmps))
{
s += "c:" + tmps + "n";
}
}
}
if (d != null)
{
s += d.ToString();
}
return s;
}
}
}
我对每个搜来的深复制方法，都用了这五个类的实例进行深复制测试，这五个类的特征如下：
I、对自定义类TestClass进行深复制测试
II、对自定义类TestClassWithS进行深复制测试，TestClassWithS是添加了Serializable特性的TestClass类
III、对DataTable进行深复制测试
IV、对控件TextBox进行深复制测试
V、对控件DataGridView进行深复制测试
我们通过实现方法DataManHelper.DeepCopyObject来进行测试
测试深复制方法1
使用二进制流的序列化与反序列化深度复制对象
public static object DeepCopyObject(object obj)
{
BinaryFormatter Formatter = new BinaryFormatter(null,
new StreamingContext(StreamingContextStates.Clone));
MemoryStream stream = new MemoryStream();
Formatter.Serialize(stream, obj);
stream.Position = 0;
object clonedObj = Formatter.Deserialize(stream);
stream.Close();
return clonedObj;
}
