一、准备Excel文件
首先我们要使用的Excel文件名test.xls或test.xlsx,如:
包含的Sheet页:
Sheet页中的内容:
二、xls读取
·核心代码:
//根据指定路径path获取文件流对象
var fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read)
//获取工作簿对象
var workbook = new HSSFWorkbook(fs);
//获取sheet页对象
var sheet = workbook.GetSheet("sheet1");
//获取指定索引index行对象
var row = sheet.GetRow(index);
//获取指定索引index单元格对象
var cell = row.GetCell(index);
完整Demo:
private static void Test1()
{
var path = @"C:\Users\ashwx\Desktop\test.xls";
if (File.Exists(path))
{
using (var fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read))
{
var workbook = new HSSFWorkbook(fs);
var sheet = workbook.GetSheet("sheet1");
if (sheet != null)
{
var row = sheet.GetRow(0);
if (row != null)
{
var cell = row.GetCell(0);
if (cell != null)
{
Console.WriteLine("{0} {1} {2}",cell.ToString(),
cell.NumericCellValue, cell.StringCellValue);
}
else
{
Console.WriteLine("cell null");
}
}
else
{
Console.WriteLine("row null");
}
}
else
{
Console.WriteLine("sheet null");
}
}
}
else
{
Console.WriteLine("file null");
}
}
三、xlsx读取
·核心代码:
//根据指定路径path获取文件流对象
var fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read)
//获取工作簿对象
var workbook = new XSSFWorkbook (fs);
//获取sheet页对象
var sheet = workbook.GetSheet("sheet1");
//获取指定索引index行对象
var row = sheet.GetRow(index);
//获取指定索引index单元格对象
var cell = row.GetCell(index)
完整Demo:
private static void Test2()
{
var path = @"C:\Users\ashwx\Desktop\1.xlsx";
if (File.Exists(path))
{
using (var fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read))
{
var workbook = new XSSFWorkbook(fs);
var sheet = workbook.GetSheet("sheet1");
if (sheet != null)
{
var row = sheet.GetRow(0);
if (row != null)
{
var cell = row.GetCell(0);
if (cell != null)
{
Console.WriteLine("{0} {1} {2}", cell.ToString(),
cell.NumericCellValue, cell.StringCellValue);
}
else
{
Console.WriteLine("cell null");
}
}
else
{
Console.WriteLine("row null");
}
}
else
{
Console.WriteLine("sheet null");
}
}
}
else
{
Console.WriteLine("file null");
}
}
四、遇到的特殊问题
如果sheet页被隐藏或不存在时,GetSheet()返回值是什么?
隐藏时,GetSheet可以正常获取非null对象;
不存在时,GetSheet返回值为null;
