I want开发者_JAVA百科 to copy two columns from excel and work on them in a c# program. What component is the best to use to mimic an excel column in a win form?
You can use the DataGridView control.
You could write a routine that pulls in clipboard data with something like:
private void pasteToolStripMenuItem_Click(object sender, EventArgs e)
{
// create dataset to hold csv data:
DataSet ds = new DataSet();
ds.Tables.Add();
ds.Tables[0].Columns.Add();
ds.Tables[0].Columns.Add();
ds.Tables[0].Columns.Add();
ds.Tables[0].Columns.Add();
ds.Tables[0].Columns.Add();
ds.Tables[0].Columns.Add();
string[] row = new string[1];
// read csv data from clipboard
IDataObject t = Clipboard.GetDataObject();
System.IO.StreamReader sr =
new System.IO.StreamReader((System.IO.MemoryStream)t.GetData("csv"));
// assign csv data to dataset
while (!(sr.Peek() == -1))
{
row[0] = sr.ReadLine();
ds.Tables[0].Rows.Add(row);
}
// set data source
dataGridView1.DataSource = ds.Tables[0];
}
Cleaned up code and tested code sample. It is still rough but demonstrates the capability with a fixed number of columns. (Pasting in more than six will crash, any less should work.)
