将 ListView 转换为数据表:
var listView1 = new ListView();
DataTable table = new DataTable();
foreach (ListViewItem item in listView1.Items)
{
table.Columns.Add(item.ToString());
foreach (var it in item.SubItems)
table.Rows.Add(it.ToString());
}
使用以下代码制作 csv:
public void CreateCSVFile(DataTable dt, string strFilePath)
{
StreamWriter sw = new StreamWriter(strFilePath, false);
int iColCount = dt.Columns.Count;
for (int i = 0; i < iColCount; i++)
{
sw.Write(dt.Columns[i]);
if (i < iColCount - 1)
{
sw.Write(",");
}
}
sw.Write(sw.NewLine);
foreach (DataRow dr in dt.Rows)
{
for (int i = 0; i < iColCount; i++)
{
if (!Convert.IsDBNull(dr[i]))
{
sw.Write(dr[i].ToString());
}
if (i < iColCount - 1)
{
sw.Write(",");
}
}
sw.Write(sw.NewLine);
}
sw.Close();
}
