Question

我正在尝试使用C#在Visual Studio Windows应用程序中读取excel文件（.xlsx）。我正在使用此链接ExcelLibrary中的Google Excel Library。我使用以下代码在按钮单击时从excel文件中读取。我在Visual Studio 2012 Professional中使用以下代码，

using ExcelLibrary.SpreadSheet;
using ExcelLibrary.BinaryDrawingFormat;
using ExcelLibrary.BinaryFileFormat;
using ExcelLibrary.CompoundDocumentFormat;

namespace ExcelRead
{
    public partial class ReadForm : Form
    {
        public ReadForm()
        {
            InitializeComponent();
        }

        private void btnRead_Click(object sender, EventArgs e)
        {
            WorkBook inputBook = Workbook.Load("D:\\Files\\input.xlsx");
            List<Worksheet> sheetList = inputBook.Worksheets;
            for (int i = 0; i < sheetList.Count; i++)
            {
                Worksheet sheet = inputBook.Worksheets[i];
                for (int rowIndex = sheet.Cells.FirstRowIndex; rowIndex <= sheet.Cells.LastRowIndex; rowIndex++)
                {
                    Row row = sheet.Cells.GetRow(rowIndex);
                    for (int colIndex = row.FirstColIndex; colIndex <= row.LastColIndex; colIndex++)
                    {
                        Cell cell = row.GetCell(colIndex);
                        Console.WriteLine(cell.ToString());
                    }
                }
            }            
        }
    }
}

但是当我运行代码并单击按钮时它会提供OutOfMemoryException was unhandled异常。它在例外中显示以下描述，

An unhandled exception of type 'System.OutOfMemoryException' occurred in mscorlib.dll

我尝试使用下面的try-catch，

try
{
    WorkBook inputBook = Workbook.Load("D:\\Files\\input.xlsx");
    List<Worksheet> sheetList = inputBook.Worksheets;
    for (int i = 0; i < sheetList.Count; i++)
    {
        Worksheet sheet = inputBook.Worksheets[i];
        for (int rowIndex = sheet.Cells.FirstRowIndex; rowIndex <= sheet.Cells.LastRowIndex; rowIndex++)
        {
            Row row = sheet.Cells.GetRow(rowIndex);
            for (int colIndex = row.FirstColIndex; colIndex <= row.LastColIndex; colIndex++)
            {
                Cell cell = row.GetCell(colIndex);
                Console.WriteLine(cell.ToString());
            }
        }
    }
}
catch (Exception err)
{
    Console.WriteLine(err);
}

但它又说了以下错误，

Adding a 'catch clause' around an active statement will prevent the debug session from continuing while Edit and Continue is enabled

我试图读取的excel文件只有18 KB，因此甚至无法使用内存不足。我不知道为什么我会得到这个例外。

Answer 1

由于您使用的是“.xlsx”文件，因此应使用GAC的“Microsoft.Office.Interop.Excel”和“Office”引用。

假设您的计算机上已安装Microsoft Office，这些应该已经安装在您的计算机上。

使用ExcelLibrary在C＃中读取Excel .xlsx文件时出现OutOfMemoryException
