Question

我想我发现了单声道的一个错误，但我没有完全隔离它，我需要帮助来解决我的问题。

重现此错误

运行csharp HelloWorld.cs
点击任意单元格
修改该单元格的内容。
点击任何其他单元格。

注意：我认为我的问题与this question有关，但更接近于隔离问题。

注意：我在单声道3.0.4和单声道3.0.1以及Linux上的单声道2.10.x上试过这个注2：我也尝试将其编译成.exe并且它仍然具有相同的错误

它将产生此调用跟踪消息：

HelloWorld.cs的内容：

using System.Data;
using System.Drawing;
using System.Windows.Forms;

public class HelloWorld : Form {
    public HelloWorld () {
        Button quit = new Button ();
        quit.Text = "quit";
        quit.Click += new EventHandler (OnClickQuit);
        quit.Location = new Point(500, 400);

        DataGridView dgv = new DataGridView();
        dgv.AutoSize = true;

        DataTable table1 = new DataTable("patients");
        table1.Columns.Add("name");
        table1.Columns.Add("id");
        table1.Rows.Add("sam", 1);
        table1.Rows.Add("mark", 2);

        DataSet ds = new DataSet("office");
        ds.Tables.Add(table1);

        dgv.DataSource = ds;
        dgv.DataMember = ds.Tables[0].TableName;
        Controls.AddRange(new Control[] { dgv, quit });
    } 
    void OnClickQuit(object sender, EventArgs e) {
        Close();
    }
}

Application.Run (new HelloWorld ());

选择DataGridView单元格时是否出现ObjectDisposedException？
