datagridview 绑定List<string>

List<string> strSource = new List<string>();

strSource.Add("one");
strSource.Add("two");
strSource.Add("three");
dataGridView1.DataSource = strSource;

结果DataGridView中显示的为什么是字符串的长度呢？

因为你没有指定DataPropertyName这个绑定字段的属性。你可以先定义一个类，例如：
public class Person
{
public Person(string _name)
{
this.name = _name;
}
private string name;
public string Name
{
get { return name; }
set { name = value; }
}
}

然后在你的DataGridView的DataPropertyName绑定name.
接下来：public List<Person> list = new List<Person>();
list.Add(new Person("张三"));
list.Add(new Person("李四"));
list.Add(new Person("王五"));
this.dataGridView1.DataSource = list;
这样就行了

IList<String> list_string= new List<String>(); DataGridView.DataSource = list_string.Select(x => new { Value = x }).ToList();

list listname = new list(); 改成 ilist listname = new list(); 这是我的你参考下 public static ilist getstuinfo() { ilist stuinfos = new list(); string sql = "select * from stuinfo"; using (datatable dt = dbhelper.getdataset(sql)) { foreach (datarow row in dt.rows) { stuinfo stu = new stuinfo(); stu.stuno=(int)row["stuno"]; stu.stuname=(string)row["stuname"]; stu.stuage = (int)row["stuage"]; stu.stuseet = (int)row["stuseet"]; stu.stusex = (string)row["stusex"]; stu.stuadress = (string)row["stuadress"]; stuinfos.add(stu); } } return stuinfos; } gridview1.datasource = bll.stuinfomanager.getstuinfo(); gridview1.databind();
