Question

问题是从我的webservice获取dataGridView中的数据。当我从webservice调用getList方法时，我得到了正确的xml代码。这是我的代码：网络服务：

[WebMethod]
    public DataSet getList()
    {
        SqlConnection connection = new SqlConnection();
        connection.ConnectionString = "server=localhost;" +
                                   "Trusted_Connection=yes;" +
                                   "database=oving1; " +
                                   "connection timeout=30";
        string select = "select * from Person";
        SqlDataAdapter da = new SqlDataAdapter(select, connection);
        DataSet ds = new DataSet();

        da.Fill(ds, "Person");
        return (ds);
    }

形式：

    private void button1_Click(object sender, EventArgs e)
    {

        Service1 webService = new Service1();
        DataSet ds = webService.getList();
        dataGridView1.DataSource = ds;


    }

您最好查看此Avoiding DataSet in Web services

通过WebServices Consuming a DataSet from an XML Web Service

序列化数据集

还有一件事是尝试将数据表传递给网格而不是数据集：

dataGridView1.DataSource = ds.Tables[0];

将数据导入dataGridView
