Question

我在将存储过程加载到DataGridView时遇到问题。我已经找到了答案，但我的代码看起来与我找到的每个答案相似。存储过程在另一个DataGridView中运行，我添加了它作为固定数据源。我是C＃的新手。谁能看到我错在哪里？

    private void Form1_Load(object sender, EventArgs e)
    {
        DataTable dt = new DataTable();
        SqlConnection myConn = new SqlConnection("Data Source=SERVER-SQL1;Initial Catalog=OPSystem;Integrated Security=True");
        myConn.Open();
        SqlCommand myCmd = new SqlCommand("spCustomers", myConn);
        myCmd.CommandType = CommandType.StoredProcedure;
        SqlDataAdapter da = new SqlDataAdapter(myCmd);
        da.Fill(dt);
        dataGridView1.DataSource = da;

    }

Answer 1

您无法绑定到SqlDataAdapter。您需要绑定到DataTable。

        DataTable dt = new DataTable();
        SqlConnection myConn = new SqlConnection("Data Source=SERVER-SQL1;Initial Catalog=OPSystem;Integrated Security=True");
        myConn.Open();
        SqlCommand myCmd = new SqlCommand("spCustomers", myConn);
        myCmd.CommandType = CommandType.StoredProcedure;
        SqlDataAdapter da = new SqlDataAdapter(myCmd);
        da.Fill(dt);
        dataGridView1.DataSource = dt;
        dataGridView1.DataBind();

对于上下文， SqlDataAdapter ：

表示一组数据命令和数据库连接用于填充DataSet并更新SQL Server数据库。这个班不能继承。

Answer 2

private BindingSource bindingSource1 = new BindingSource（）;

DataTable dt = new DataTable（）;

SqlConnection myConn = new SqlConnection（＆＃34; Data Source = SERVER-SQL1; Initial Catalog = OPSystem; Integrated Security = True＆＃34;）;

    myConn.Open();
    SqlCommand myCmd = new SqlCommand("spCustomers", myConn);
    myCmd.CommandType = CommandType.StoredProcedure;
    SqlDataAdapter da = new SqlDataAdapter(myCmd);
    da.Fill(dt);

bindingSource1.DataSource = dt; dataGridView1.DataSource = bindingSource1;

尝试使用BindingSource

从存储过程加载DataGridView
