修改 MSI 数据库属性的问题 [英] Problem with modifying an MSI database property

问题描述

我需要通过 C# 修改 Upgrade MSI 表的 UpgradeCode 属性.此代码适用于其他表的属性，但在我尝试修改这些属性时会引发错误.

I need to modify the UpgradeCode property of the Upgrade MSI table via C#. This code works ok with other tables' properties, but throws an error when I'm trying to modify these.

using (var database = new Database(TEMPDATABASE, DatabaseOpenMode.Direct))        
{
    string upgradeCode = Guid.NewGuid().ToString("B").ToUpper();
    database.Execute("Update `Upgrade` Set `Upgrade`.`UpgradeCode` = '{0}'", upgradeCode);
}

错误是:

Microsoft.Deployment.WindowsInstaller.InstallerException: '函数在执行过程中失败.'

Microsoft.Deployment.WindowsInstaller.InstallerException: 'Function failed during execution.'

推荐答案

我感到好奇和掠夺 github.com - 它给出了以下内容:完整项目 - 只需将其作为一个整体下载即可.

I got curious and pillaged github.com - and it giveth the following: Full project - just download it as a whole.

实际代码是(github.com 上的文件中的一些 unicode 换行问题，我已修复他们在这里):

The actual code was (some unicode line feed issues in the file on github.com, I have fixed them up here):

public static void UpdateUpgradeTable(this Database db, Guid upgradeCode)
{
    using (View view = db.OpenView("SELECT * FROM `Upgrade`", new object[0]))
    {
        view.Execute();
        using (Record record = view.Fetch())
        {
            record[1] = upgradeCode.ToString("B").ToUpperInvariant();
            view.Replace(record);
        }

        db.Commit();
    }
}

我根据上面的内容制作了以下模型(非常丑陋，但确实有效):

I took the above and made the following mock-up (very ugly, but it worked):

using (Database db = new Database(@"C:\Test.msi", DatabaseOpenMode.Direct))
{
    using (View view = db.OpenView("SELECT * FROM `Upgrade`", new object[0]))
    {
        view.Execute();
        using (Record record = view.Fetch())
        {
            record[1] = "{777888DD-1111-1111-1111-222222222222}";
            record[2] = "";
            record[3] = "4.0.1";
            record[4] = "";
            record[5] = "1";
            record[6] = "";
            record[7] = "WIX_UPGRADE_DETECTED";
            view.Replace(record);
        }

        db.Commit();

        using (Record record = view.Fetch())
        {
            record[1] = "{777888DD-1111-1111-1111-222222222222}";
            record[2] = "";
            record[3] = "";
            record[4] = "4.0.1";
            record[5] = "1";
            record[6] = "";
            record[7] = "WIX_DOWNGRADE_DETECTED";
            view.Replace(record);
        }

        db.Commit();
    }
}
