Serializable数据,然后客户端反序列化,存入dataset
再绑定到datagrid
////////////////////////////////////////////////////////////
dataGridView怎么直接绑定数据库的表格？
private DataSet dataset = new DataSet();
private SqlDataAdapter DataAd;
DBhelper.conn.Open();
string sql = "";
DataAd = new SqlDataAdapter(sql, DBhelper.conn);
DataAd.Fill(dataset, "");
dataGridView1.DataSource = dataset.Tables[""];
SqlCommandBuilder builder = new SqlCommandBuilder(DataAd);
DataAd.Update(dataset, "");
DataSet1.Tables[ "表名 "].Select( "ID，NAME，DTIME where NAME= '某值 ' ") //对dataset表进行取值操作
DBhelper.conn.Close();

日前做一项目，access数据库，里边包含众多类似数据库，要求datagridview能够根据用户选择绑定指定数据库：
using System.IO;
using System.Diagnostics;
using System.Data.OleDb;
1.把所有的表列举到treeview控件中
treeView1.Nodes.Clear();
//list all datatables
OleDbConnection connection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + cn_str.get_con_string + ";Persist Security Info=False");
connection.Open();
DataTable dtSchema = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new Object[] { null, null, null, "TABLE" });
for (int i = 0; i < dtSchema.Rows.Count; i++)
{
TreeNode newnode1 = new TreeNode();
newnode1.Text = dtSchema.Rows[i]["TABLE_NAME"].ToString();
//add to the treenode
treeView1.Nodes.Add(newnode1);
}
2.用户选择数据库
if (treeView1.SelectedNode != null)
{
cn_str.set_con_string = treeView1.SelectedNode.Text.ToString();
}
3.绑定数据库
OleDbConnection connection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + cn_str.get_con_string + ";Persist Security Info=False");
connection.Open();
DataSet ds = new DataSet();
string sql = "select * from " + cn_str.set_con_string;
OleDbDataAdapter da = new OleDbDataAdapter(sql, connection);
da.Fill(ds);
connection.Close();
GQ_DATA.DataSource = ds.Tables[0];
*其中，cn_str.get_con_string --表示选择的数据库
cn_str.set_con_string --表示选择的表
