如何分割導入的文本內容？

listView1.View = View.Details;//設置視圖為詳細信息

ColumnHeader header1 = new ColumnHeader();

header1.Width = 100; //列標頭寬

header1.Text = "第一列"; //列標頭名稱

ColumnHeader header2 = new ColumnHeader();

header2.Width = 100;

header2.Text = "第二列";

listView1.Columns.Add(header1);//添加列

listView1.Columns.Add(header2);

string path = @"G:\2.txt";//文件路徑

using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read))

{

using (Streamreader reader = new StreamReader(fs, Encoding.Default))

{

string line = reader.ReadLine();

while (line != null)

{

string[] arr = line.Split(new string[] { "----" }, StringSplitOptions.None);

listView1.Items.Add(new ListViewItem(arr));

line = reader.ReadLine();

}

}

}
