如何将网格视图数据导出到Ms访问数据库。
我会尝试下面的代码:
private void ExportGridToAccess()
{
Response.ContentType = "application/ms-access";
Response.AddHeader("content-disposition", "attachment; filename=Vithal_Wadje.mdb");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridView1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document AccessDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
HTMLWorker htmlparser = new HTMLWorker(AccessDoc);
PdfWriter.GetInstance(AccessDoc, Response.OutputStream);
AccessDoc.Open();
htmlparser.Parse(sr);
AccessDoc.Close();
Response.Write(AccessDoc);
Response.End();
GridView1.AllowPaging = true;
GridView1.DataBind();
}
但是当我打开时下载文件:无法识别的数据库格式。正在显示警告

using ADOX;
protected void btnacess_Click(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("Student_ID", typeof(Int32));
dt.Columns.Add("Student_Name", typeof(string));
dt.Columns.Add("Education", typeof(string));
dt.Columns.Add("City", typeof(string));
DataRow dtrow = dt.NewRow();
dtrow["Student_ID"] = 1;
dtrow["Student_Name"] = "Musakkhir";
dtrow["Education"] = "MCA";
dtrow["City"] = "Pune";
dt.Rows.Add(dtrow);
dtrow = dt.NewRow();
dtrow["Student_ID"] = 2;
dtrow["Student_Name"] = "Azhar";
dtrow["Education"] = "M.E";
dtrow["City"] = "Mumbai";
dt.Rows.Add(dtrow);
dtrow = dt.NewRow();
dtrow["Student_ID"] = 3;
dtrow["Student_Name"] = "Pervaiz";
dtrow["Education"] = "M.Tech";
dtrow["City"] = "Pune";
dt.Rows.Add(dtrow);
dtrow = dt.NewRow();
dtrow["Student_ID"] = 4;
dtrow["Student_Name"] = "Mustaheer";
dtrow["Education"] = "M.S.";
dtrow["City"] = "Pune";
dt.Rows.Add(dtrow);
GridView1.DataSource = dt;
GridView1.DataBind();
ADOX.Catalog cat = new ADOX.Catalog();
ADOX.Table table = new ADOX.Table();
//Create the table and it's fields.
table.Name = "Table1";
table.Columns.Append("PartNumber", ADOX.DataTypeEnum.adVarWChar, 60); // text[6]
table.Columns.Append("AnInteger", ADOX.DataTypeEnum.adInteger, 10); // Integer
try
{
cat.Create("Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=d:/m11.mdb;" + "Jet OLEDB:Engine Type=5");
cat.Tables.Append(table);
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;" + "Data Source=d:/m11.mdb");
int i = GridView1.Rows.Count;
for (int j = 0; j <= i; j++)
{
conn.Open();
OleDbCommand cmd = new OleDbCommand();
cmd.Connection = conn;
cmd.CommandText = "INSERT INTO Table1([PartNumber],[AnInteger]) VALUES (@FirstName,@LastName)";
cmd.Parameters.Add("@FirstName", OleDbType.VarChar).Value = GridView1.Rows[j].Cells[1].Text;
cmd.Parameters.Add("@LastName", OleDbType.VarChar).Value = GridView1.Rows[j].Cells[0].Text;
cmd.ExecuteNonQuery();
conn.Close();
}
}
catch (Exception ex)
{
}
cat = null;
}
这将通过这种方式解决
