NPOI读取数据，创建filestream实例时总是出错
这是代码using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using NPOI.HSSF.UserModel;
using NPOI.HPSF;
using NPOI.POIFS.FileSystem;
using System.IO;
using NPOI.SS.UserModel;
namespace XLS实验
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
if (openFile.ShowDialog() == DialogResult.OK)
{
int[] bianhao = new int;
string path = "";
path = openFile.FileName;
FileStream fs = File.Open(path,FileMode.Open);
HSSFWorkbook myxls = new HSSFWorkbook(fs);
ISheet mysheet = myxls.GetSheet("sheet1");
StringBuilder sb = new StringBuilder("");
for (int i = 0; i <= 225; i++)
{
IRow row = mysheet.GetRow(i + 2);
ICell cell=row.GetCell(1);
bianhao = (int)cell.NumericCellValue;
for(int j=0;j<=225;j++)
{
this.textBox1.Text+= bianhao.ToString();
}
}
fs.Close();
}
}
}
}
每次到FileStream fs = File.Open(path,FileMode.Open);就会出错
我换过FileStream fs = new FileStream(path,FileMode.Open，FileAccess.Read); 还是同样出错
报的什么错
