如何使用c＃压缩Msaccess数据库＃

Question

是否可以使用c＃压缩Msaccess数据库，如果让我知道方式？

Answer 1

你可以尝试这样的

public static void CompactAndRepair(string accessFile, Microsoft.Office.Interop.Access.Application app) 
     { 
      string tempFile = Path.Combine(Path.GetDirectoryName(accessFile), 
           Path.GetRandomFileName() + Path.GetExtension(accessFile)); 

      app.CompactRepair(accessFile, tempFile, false); 
      app.Visible = false; 

      FileInfo temp = new FileInfo(tempFile); 
      temp.CopyTo(accessFile, true); 
      temp.Delete(); 
     } 

看到的东西也Use the CompactRepair method of the Application object to compact and repair the database

Answer 2

... 
//invoke a CompactDatabase method of a JRO object 
//pass Parameters array 
objJRO.GetType().InvokeMember("CompactDatabase", 
    System.Reflection.BindingFlags.InvokeMethod, 
    null, 
    objJRO, 
    oParams); 
...

我曾经在文章：
Compact and Repair an Access Database Programmatically Using C#

我修改了它一下，使其更易于使用：

public static bool CompactAndRepairAccessDB(string source, string destination) 
{ 
    try 
    { 
     JetEngine engine = (JetEngine)HttpContext.Current.Server.CreateObject("JRO.JetEngine"); 
     engine.CompactDatabase(string.Format("Data Source={0};Provider=Microsoft.Jet.OLEDB.4.0;", source), 
      string.Format("Data Source={0};Provider=Microsoft.Jet.OLEDB.4.0;", destination)); 
     File.Copy(destination, source, true); 
     File.Delete(destination); 
     return true; 
    } 
    catch 
    { 
     return false; 
    } 
} 

不要忘记：在Solution Explorer
右键单击参考 - >添加引用 - > COM - >搜索 '喷气机' - >添加“的Microsoft Jet和复制对象......”

，并添加：

using System.IO; 
using JRO;
