c#datasource返回System.Data.DataRowView

Question

我有一个组合框cbAnalytes:

cbAnalytes.DataSource = ConnectandReadList(qcvalues_query);

ConnectandReadList的位置是:

public DataTable ConnectandReadList(string query)
{
    DataTable ds = new DataTable();
    string connection_string = "Data Source=hermes;database=qcvalues; Integrated Security=SSPI;";
    using (var myConnection = new SqlConnection(connection_string))
    {
        myConnection.Open();
        var command = new SqlCommand(query, myConnection);
        var adapter = new SqlDataAdapter(command);
        adapter.Fill(ds);
    }
    return ds;
}

由于某种原因,它填充组合框:

System.Data.DataRowView
System.Data.DataRowView
System.Data.DataRowView
System.Data.DataRowView
System.Data.DataRowView

有谁知道我做错了什么？

你在设置你的属性DisplayMember和ValueMember属性是什么？您需要为组合框设置这些属性,以便它知道要显示的内容.
