Question

我正在构建Windows窗体C＃应用程序。我需要从Excel文档中读取希伯来语文本，然后做一些事情，然后将一些希伯来语文本写入Word文档。目前，我无法从Excel读取希伯来语（将其打印到控制台时出现问号）。我知道这个问题与编码问题有关。

代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using System.Runtime.InteropServices;
using Excel = Microsoft.Office.Interop.Excel;

namespace MLDRApplication
{
    public class ExcelReader
    {
        public static List<Customer> ExcelReadergetCustomers(string path)
        {
            List<Customer> customersList = new List<Customer>();
            //Create COM Objects. Create a COM object for everything that is referenced
            Excel.Application excelApp = new Excel.Application();
            Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(@"C:\Users\fares\OneDrive\Documents\customersInitValues.xlsx");
            Excel.Worksheet customersWorksheet = excelWorkbook.Sheets[1];
            Excel.Worksheet laundryUnitsWorksheet = excelWorkbook.Sheets[2];


            Excel.Range customersRange = customersWorksheet.UsedRange;
            Excel.Range laundryUnitsRange = laundryUnitsWorksheet.UsedRange;

            int customersSheetRowCount = customersRange.Rows.Count;
            int customersSheetColCount = customersRange.Columns.Count;
            int laundryUnitsSheetRowCount = laundryUnitsRange.Rows.Count;
            int laundryUnitsSheetColCount = laundryUnitsRange.Columns.Count;



            //iterate over the rows and columns and print to the console as it appears in the file
            //excel is not zero based!!
            for (int i = 1; i <= customersSheetRowCount; i++)
            {
                for (int j = 1; j <= customersSheetColCount; j++)
                {
                    //new line
                    if (j == 1)
                        Console.Write("\r\n");

                    //write the value to the console
                    //Console.OutputEncoding = System.Text.Encoding.GetEncoding("Windows-1255");
                    if (customersRange.Cells[i, j] != null && customersRange.Cells[i, j].Value2 != null)
                    {
                        //customersList.Add()
                        Console.Write(customersRange.Cells[i, j].Value2.ToString() + "\t");
                    }
                }

            }

            for (int i = 1; i <= laundryUnitsSheetRowCount; ++i)
            {
                for (int j = 1; j <= laundryUnitsSheetColCount; ++j)
                {
                    //new line
                    if (j == 1)
                        Console.Write("\r\n");

                    //write the value to the console
                    //Console.OutputEncoding = System.Text.Encoding.GetEncoding("Windows-1255");
                    if (laundryUnitsRange.Cells[i, j] != null && laundryUnitsRange.Cells[i, j].Value2 != null)
                    {
                        //customersList.Add()
                        Console.Write(laundryUnitsRange.Cells[i, j].Value2.ToString() + "\t");
                    }
                }

            }

            //cleanup
            GC.Collect();
            GC.WaitForPendingFinalizers();

            //rule of thumb for releasing com objects:
            //  never use two dots, all COM objects must be referenced and released individually
            //  ex: [somthing].[something].[something] is bad

            //release com objects to fully kill excel process from running in the background
            Marshal.ReleaseComObject(customersRange);
            Marshal.ReleaseComObject(customersWorksheet);
            Marshal.ReleaseComObject(laundryUnitsRange);
            Marshal.ReleaseComObject(laundryUnitsWorksheet);


            //close and release
            excelWorkbook.Close();
            Marshal.ReleaseComObject(excelWorkbook);

            //quit and release
            excelApp.Quit();
            Marshal.ReleaseComObject(excelApp);

            return customersList;



        }
    }
}

我阅读了本次会议here，但不了解此问题并获得正确的解决方案。

您的问题不在阅读中。
这是因为控制台应用程序的默认编码不支持希伯来语。

在控制台应用程序中，您可以更改编码，在代码开头添加以下行：

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

<div id="card1" style="width: 100px; height: 100px; background-color: red;"></div>
<h4 id="artist1" class="artistname ">testname</h4>

编辑：显然

您不能在控制台中打印Unicode字符，它仅支持当前代码页中可用的字符。性格不可用的将转换为最接近的等效项，或者问号。

所以您可以做一个小的“ hack”，只需将默认输出流更改为一个文件：

Console.OutputEncoding = Encoding.GetEncoding("Windows-1255");

，并在运行结束时将所有内容写入其中。

这是一个“快速而肮脏的” 解决方案，用于永久解决方案，考虑将日志记录库用作log4net。
