【问题描述】:
在获取读取xml的简单方法方面需要帮助。 以下是我采取的步骤:
- 添加了来自 Microsoft Excel 12.0 对象库 COM 的引用。
- 完全从另一个来源复制代码 http://csharp.net-informations.com/excel/csharp-read-excel.htm
- 唯一的区别是我要求这是一种方法而不是 onclick 事件。
- 我得到的错误是错误 10 代码
releaseObject(xlWorkSheet); releaseObject(xlWorkBook); releaseObject(xlApp);上的非静态字段、方法或属性需要对象引用
需要哪些步骤?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Excel = Microsoft.Office.Interop.Excel;
namespace projectName
{
class frmReadXml
{
public static void executeRead()
{
Excel.Application xlApp = new Excel.Application();
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet = new Excel.Worksheet();
Excel.Range range;
string str;
int rCnt = 0;
int cCnt = 0;
xlWorkBook = xlApp.Workbooks.Open("csharp.net-informations.xls", 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
range = xlWorkSheet.UsedRange;
for (rCnt = 1; rCnt <= range.Rows.Count; rCnt++)
{
for (cCnt = 1; cCnt <= range.Columns.Count; cCnt++)
{
str = (string)(range.Cells[rCnt, cCnt] as Excel.Range).Value2;
MessageBox.Show(str);
}
}
xlWorkBook.Close(true, null, null);
xlApp.Quit();
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);
}
private void releaseObject(object obj)
{
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
obj = null;
}
catch (Exception ex)
{
obj = null;
MessageBox.Show("Unable to release the Object " + ex.ToString());
}
finally
{
GC.Collect();
}
}
}
}
