为了查看我们为tis上传的excel文件的内容，我们应该遵循以下代码：

{

OleDbConnection theConnection = new OleDb连接（provider = Microsoft.Jet.OLEDB.4.0; data source = books.xls; Extended Properties = \Excel 8.0; HDR = NO; IMEX = 1; \）;

theConnection.Open（）;

OleDbDataAdapter theDataAdapter = new OleDbDataAdapter（SELECT * FROM [Sheet1

For Viewing the content of the excel file which we uploaded for tis we should follow the below code:
{
OleDbConnection theConnection = new OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0;data source=books.xls;Extended Properties=\"Excel 8.0;HDR=NO;IMEX=1;\"");
theConnection.Open();
OleDbDataAdapter theDataAdapter = new OleDbDataAdapter("SELECT * FROM [Sheet1

，theConnection）;

DataSet theDS = new DataSet（）;

DataTable dt = new DataTable（）;

theDataAdapter.Fill（dt）;

this。 dataGridView1.DataSource = dt.DefaultView;

}



要将Excel文件上传到C＃windows应用程序表单，我们应该遵循以下代码：

{

OpenFileDialog fDialog = new OpenFileDialog（）;

fDialog.Title =选择要上传的文件;

fDialog.Filter =（* .xls）| * .xls;

if（fDialog.ShowDialog（）== DialogResult.OK）

{

txtFileName.Text = fDialog.FileName.ToString（）;

}

", theConnection);
DataSet theDS = new DataSet();
DataTable dt = new DataTable();
theDataAdapter.Fill(dt);
this.dataGridView1.DataSource = dt.DefaultView;
}

For uploading a Excel file into C# windows application form we should follow the below code:
{
OpenFileDialog fDialog = new OpenFileDialog();
fDialog.Title = "Select file to be upload";
fDialog.Filter = "(*.xls)|*.xls";
if (fDialog.ShowDialog() == DialogResult.OK)
{
txtFileName.Text = fDialog.FileName.ToString();
}
