我已经编写了网格视图的代码,将其更改为列表。我认为这会有所帮助
protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile)
{
string s = FileUpload1.FileName.Trim();
if (s.EndsWith(".csv"))
{
FileUpload1.PostedFile.SaveAs(Server.MapPath("~/data/" + s));
string[] readText = File.ReadAllLines(Server.MapPath("~/data/" + s));
DataSet ds = new DataSet();
DataTable dt = new DataTable();
// Array.Sort(readText);
for (int i = 0; i < readText.Length; i++)
{
if (i == 0)
{
string str = readText[0];
string[] header = str.Split(',');
dt.TableName = "sal";
foreach (string k in header)
{
dt.Columns.Add(k);
}
}
else
{
DataRow dr = dt.NewRow();
string str1 = readText[i];
if (readText[i] == ",,,,")
{
break;
}
string[] rows = str1.Split(',');
if (dt.Columns.Count == rows.Length)
{
for (int z = 0; z < rows.Length; z++)
{
if (rows[z] == "")
{
rows[z] = null;
}
dr[z] = rows[z];
}
dt.Rows.Add(dr);
}
else
{
Label1.Text = "please select valid format";
}
}
}
//Iterate through the columns of the datatable to set the data bound field dynamically.
ds.Merge(dt);
Session["tasktable"] = dt;
foreach (DataColumn col in dt.Columns)
{
BoundField bf = new BoundField();
bf.DataField = col.ToString();
bf.HeaderText = col.ColumnName;
if (col.ToString() == "Task")
{
bf.SortExpression = col.ToString();
}
GridView1.Columns.Add(bf);
}
GridView1.DataSource = ds;
GridView1.DataBind();
}
else
{
Label1.Text = "please select a only csv format";
}
}
else
{
Label1.Text = "please select a file";
}
}
