DataView绑定数据不区分大小写

[langmafeng]

public class TestView
{
private String m_Test;
public String Test
{
get { return m_Test; }
set { m_Test = value; }
}
private Int32 m_TEST;
public Int32 TEST
{
get { return m_TEST; }
set { m_TEST = value; }
}
}

TestView[] testViews = new TestView[2];
TestView testView = new TestView();
testView.TEST = 1;
testView.Test = "a";
testViews[0] = testView;
testView = new TestView();
testView.TEST = 2;
testView.Test = "b";
testViews[1] = testView;
this.dataGridView1.DataSource = testViews;

运行后的结果居然是这样的：


看来DataGridView绑定数据时内部通过通过反射获取数据时是不区分大小写的
算不算BUG呢？
现在修改类的定义不太可能，这两天还在找解决方案，研究中...

？？

你挂的图看不到 但是我这里代码运行出来 没有任何问题

[langmafeng]

[bitsbird]

哪里有反射？

[jiatong1981]

…… 肯定是你代码里有问题

不会出现这种bug的

呵呵 应该说这是你的bug

[我去呀]

你写的代码有问题，这样写试试
TestView[] testViews = new TestView[2];
testViews[0].TEST = 1;
testViews[0].Test ="a";
testViews[1].TEST = 2;
testViews[1].Test = "b ";
this.dataGridView1.DataSource = testViews;

[我去呀]

按你的方法testViews[0]和testViews[1]指向的是同一个对象

[hooo]

竟然不区分大小写。。
看来是bug吧

[langmafeng]

Re 3楼：DataGridView内部取数据的时候肯定用到了反射
Re 4楼：为了测试方便以及测试结果的准确性，我专门建了一个空的测试项目，代码都帖出来了

[fellowcheng]

好象是有这个问题
不过也难免，sqlserver的列就是不分大小写的

[jiatong1981]

……

为什么我就没有

[我自横刀香甜笑]

没做过这样的事情，你为什么要做成这样的呢？你区分了不就行了？

原因很复杂，你的观点不在本帖讨论范围之内
