相似示例2

这是填充我的datagridview的代码...

Here is the code that populates my datagridview...

XElement xdoc = XElement.Load(@"C:\xmltest\test.xml");

            var lines = from item in xdoc.Descendants("line")
                        let fields = item.Elements("field")
                        select new
                        {
                            Name = (string)fields
                                .FirstOrDefault(n => (string)n.Attribute("name") == "Name"),
                            Description = (string)fields
                                .FirstOrDefault(n => (string)n.Attribute("name") == "Description"),
                            ExtraDetails = (string)fields
                                .FirstOrDefault(n => (string)n.Attribute("name") == "ExtraDetails"),

                        };


            dataGridView1.DataSource = lines.ToArray();

这工作正常，但是在导入"之后我无法编辑datagridview.我已经严格地设置了datagridview设置以允许编辑等.问题似乎与databind有某种联系.

This works fine but I can't edit the datagridview after the 'import'. I have defiantly set the datagridview settings to allow editing etc. The problem seems to be related to the databind in some way.

推荐答案

问题是您将结果投影到

The problem is that you are projecting the result to anonymous type. The very first line in the documentation link states

匿名类型提供了一种方便的方法，可以将一组只读属性封装到单个对象中，而不必先明确定义一个类型.

Anonymous types provide a convenient way to encapsulate a set of read-only properties into a single object without having to explicitly define a type first.

希望您注意到只读一词.

如果要获取可编辑的数据，请创建具有读取/写入属性的类，并将查询结果投影到其中.

If you want to get editable data, then create your own class with read/write properties and project the query result into it.
