C#数据恢复出现的错误
代码如下:
private void 数据恢复ToolStripMenuItem_Click(object sender, EventArgs e)
{
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{


this.label1.Visible = true;
this.label1.Refresh();
this.progressBar1.Visible = true;
this.groupBox1.Visible = true;
this.label1.Text = "进行数据库恢复中... ";
SQLDMO.SQLServer svr = new SQLDMO.SQLServerClass();
//try
//{
svr.Connect( "127.0.0.1 ", "sa ", " ");
//杀死所有有关的进程
SQLDMO.QueryResults qr = svr.EnumProcesses(-1);
int iColPIDNum = -1;
int iColDbName = -1;
for (int i = 1; i <= qr.Columns; i++)
{
string strName = qr.get_ColumnName(i);
if (strName.ToUpper().Trim() == "SPID ") iColPIDNum = i;
else if (strName.ToUpper().Trim() == "DBNAME ") iColDbName = i;

if (iColPIDNum != -1 && iColDbName != -1) break;
}

for (int i = 1; i <= qr.Rows; i++)
{
int lPID = qr.GetColumnLong(i, iColPIDNum);
string strDBName = qr.GetColumnString(i, iColDbName);
if (strDBName.ToUpper() == strDBName.ToUpper()) svr.KillProcess(lPID); \\提示此处发生错误,[Microsoft][ODBC SQL Server Driver][SQL Server]只能取消用户进程。
}

SQLDMO.Restore res = new SQLDMO.RestoreClass();
res.Action = 0;
SQLDMO.RestoreSink_PercentCompleteEventHandler pceh = new SQLDMO.RestoreSink_PercentCompleteEventHandler(Step);
res.PercentComplete += pceh;
res.Files = openFileDialog1.FileName.Trim();
res.Database = "test ";
res.ReplaceDatabase = true;
res.SQLRestore(svr);
MessageBox.Show( "数据库恢复成功! ", "系统提示！ ", MessageBoxButtons.OK, MessageBoxIcon.Warning);

//}
//catch (Exception err)
//{
// throw (new Exception( "恢复数据库失败,请关闭所有和该数据库连接的程序!\n如果在桌面进行恢复请改变路径!\n\n " + err.Message));
//}
//finally
//{
svr.DisConnect();
//}
this.groupBox1.Visible = false;
this.label1.Visible = false;
this.progressBar1.Visible = false;

}
}

无法实现数据库恢复...哪为大虾指教下.这个代码是晚上找的,稍做了修改..自己并不是非常理解.


[解决办法]
public string dataRestore(string strDbName, string filepath)//strDbName数据库名称，filepath备份文件路径
{
SQLDMO.Restore oRestore = new SQLDMO.RestoreClass();
SQLDMO.SQLServer oSQLServer = new SQLDMO.SQLServerClass();
try
{
oSQLServer.LoginSecure = false;
oSQLServer.Connect( "localhost ", "sa ", " ");
SQLDMO.QueryResults qr = oSQLServer.EnumProcesses(-1);
int iColPIDNum = -1;
int iColDbName = -1;
for (int i = 1; i <= qr.Columns; i++)
{
string strName = qr.get_ColumnName(i);
if (strName.ToUpper().Trim() == "SPID ")
{
iColPIDNum = i;
}
else if (strName.ToUpper().Trim() == "DBNAME ")
{
iColDbName = i;
}
if (iColPIDNum != -1 && iColDbName != -1)
break;
}

for (int i = 1; i <= qr.Rows; i++)
{
int lPID = qr.GetColumnLong(i, iColPIDNum);
string strDBName = qr.GetColumnString(i, iColDbName);
if (strDBName.ToUpper() == strDbName.ToUpper())
oSQLServer.KillProcess(lPID);
}

oRestore.Action = SQLDMO.SQLDMO_RESTORE_TYPE.SQLDMORestore_Database;
oRestore.Database = strDbName;
oRestore.Files = filepath;
oRestore.FileNumber = 1;
oRestore.ReplaceDatabase = true;
oRestore.SQLRestore(oSQLServer);
return "恢复数据库成功 ";
}
catch (Exception ee)
{
System.Web.HttpContext.Current.Response.Write(ee.Message);
return "恢复数据库失败 ";
}
finally
{
oSQLServer.DisConnect();
}

}

这是我用的还原数据库的函数，你试试吧
