如何绑定 List<string>到 DataGridView 控件? [英] How to bind a List&lt;string&gt; to a DataGridView control?

问题描述

我有一个简单的 List，我希望它显示在 DataGridView 列中.
如果列表将包含更复杂的对象，只需将列表建立为其 DataSource 属性的值.

I have a simple List<string> and I'd like it to be displayed in a DataGridView column.
If the list would contain more complex objects, simply would establish the list as the value of its DataSource property.

但是这样做时:

myDataGridView.DataSource = myStringList;

我得到一个名为 Length 的列，并显示字符串的长度.

I get a column called Length and the strings' lengths are displayed.

如何在列中显示列表中的实际字符串值?

推荐答案

那是因为 DataGridView 查找包含对象的属性.对于字符串，只有一个属性——长度.所以，你需要一个像这样的字符串的包装器

Thats because DataGridView looks for properties of containing objects. For string there is just one property - length. So, you need a wrapper for a string like this

public class StringValue
{
    public StringValue(string s)
    {
        _value = s;
    }
    public string Value { get { return _value; } set { _value = value; } }
    string _value;
}

然后将 List 对象绑定到您的网格.它有效

Then bind List<StringValue> object to your grid. It works
