wpf datatable列名称不能有斜杠/ [英] wpf datatable column name can not have slash /

问题描述

我是WPF的新手.我有一个很奇怪的问题，就是要做一张桌子，这是我的代码:

I'm very new to WPF. I'm having a very weird issue to just make a table, here is the code I have:

DataTable table = new DataTable();
table.Columns.Add("request/sec", typeof(string));
DataRow newRow = dataTable.NewRow();
newRow["request/sec", "na");

但是它只显示带有"request/sec"的列名和一个空行

but it only shows a column name with "request/sec" and an empty row

但是，如果我这样做:

DataTable table = new DataTable();
table.Columns.Add("test(request/sec)", typeof(string));
DataRow newRow = dataTable.NewRow();
newRow["test(request/sec)", "na");

然后它可以正常工作，它正确显示了列名，并显示了一个值为"na"的行

then it's working, it shows the column name correctly, and a row with value "na"

我不知道为什么会这样，我知道这听起来很荒谬.有人可以帮忙吗?

I have no idea why this is happening, I know it sounds ridiculously. Can anyone help?

注意:我也尝试过"//"，"/"，"\/"，@我无法对列名进行硬编码，它是由某些逻辑动态生成的，我以上面的代码为例

note: I also tried "//", "/", "\/", @ I can not hardcoded the column names, it's dynamic generated by certain logic, I used the above code as examples

推荐答案

当属性名称包含某些保留字符(如.和/)时，创建绑定会出现问题.属性路径解析器只是不处理它们.您有两种选择:

There are issues creating bindings when a property name contains some reserved characters like . and /. The property path parser just doesn't handle them. You have a couple options:

1. 不是让网格自动生成列，而是自己定义它们，对于具有保留字符的列，请绑定到数据行的索引器而不是列名称:

1. Instead of having the grid automatically generate the columns, define them yourself, and for columns with reserved characters, bind to the data row's indexer instead of the column name:

<DataGridTextColumn Binding="{Binding Path=[request/sec]}" Header="request/sec" />

如果仅因为要控制列标题文本而只关心列名称，只需手动声明列，为列指定合法"名称，然后设置 Header 就像上面一样.
