C# 修复Access数据库的一个范例程序
C# 修复Access数据库的一个范例程序,不过不知道到底能不能修复吧,这个修复过程的编写,可参考以下代码:
//声明临时数据库的名称
string temp = DateTime.Now.Year.ToString();
temp += DateTime.Now.Month.ToString();
temp += DateTime.Now.Day.ToString();
temp += DateTime.Now.Hour.ToString();
temp += DateTime.Now.Minute.ToString();
temp += DateTime.Now.Second.ToString() + ".bak";
temp = strPathMdb.Substring(0, strPathMdb.LastIndexOf("") + 1) + temp;
//定义临时数据库的连接字符串
string temp2 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + temp;
//定义目标数据库的连接字符串
string strPathMdb2 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + strPathMdb;
JRO.JetEngineClass jt = new JRO.JetEngineClass();//创建一个JetEngineClass对象
//使用JetEngineClass对象的CompactDatabase方法压缩修复数据库
jt.CompactDatabase(strPathMdb2, temp2);
File.Copy(temp, strPathMdb, true);//拷贝临时数据库到目标数据库(覆盖)
File.Delete(temp);//删除临时数据库
MessageBox.Show("修复完成");
这个程序中使用了三个类库:Interop.ADODB.dll、Interop.ADOX.dll、Interop.JRO.dll。
