请帮我看看上面有什么错误吗？（目的打开txt，把txt存到datatable里）
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "所有文本文件(*.txt)|*.txt";
openFileDialog1.FileName = "";
DialogResult result = openFileDialog1.ShowDialog();

if (result == DialogResult.OK)
{
//找到需要的文本，获取了文件名
string filepath = openFileDialog1.FileName;
txtPath.Text = filepath;
}

private DataTable MakeQQqunTable(string path)
{

column1.DataType = System.Type.GetType("System.String");
column1.ColumnName = "QQ";
table.Columns.Add(column1);

DataColumn column2 = new DataColumn();
column2.DataType = System.Type.GetType("System.String");
column2.ColumnName = "shouji";
table.Columns.Add(column2);

DataColumn column3 = new DataColumn();
column3.DataType = System.Type.GetType("System.String");
column3.ColumnName = "guanjianci";
table.Columns.Add(column3);



// Instantiate the DataSet variable.
dataSet = new DataSet();
// Add the new DataTable to the DataSet.
dataSet.Tables.Add(table);

// Create three new DataRow objects and add
// them to the DataTable
StreamReader reader = new StreamReader(path);

for (int i = 0; i<table.Rows.Count; i++)
{
string str = "";
str = reader.ReadLine();
//string[] s = str.Split(';');

if (!string.IsNullOrEmpty(str))
{
string[] s = str.Split(new[] { ";" }, StringSplitOptions.RemoveEmptyEntries);
//string[] s = str.Split(';');
DataRow row = table.NewRow();
row["QQ"] = s[0].ToString().Trim();
row["LEI"] = s[1].ToString().Trim();
row["guanjianci"] = txtQunguanjianci.Text;

table.Rows.Add(row);
}
else
break;
}
reader.Close();
label8.Text = table.Rows.Count.ToString();
return table;
}

[解决办法]
for (int i = 0; i<table.Rows.Count; i++)

这句话错了，读文件之前，table的行数是0；所以程序不会执行到循环内部；
