您好，

您可以获取安装路径在自定义操作中，执行以下步骤：

You can get the installation path in the Custom Actions with the following steps:

步骤1 ：通过右键单击将主要输出添加到"安装"选项：

Step 1: Add your primary output to the Install selection by righting click:

第2步：然后将 / DIR ="[TARGETDIR] \" 添加到CustomActionData属性中：

Step 2: Then add /DIR="[TARGETDIR]\" to the CustomActionData property:

第3步：在您的网站上添加安装类project并获取如下路径：

Step 3: Add a install class to your project and get the path as below:

    [RunInstaller(true)]
    public class MyInstaller : Installer
    {
        public override void Install(System.Collections.IDictionary stateSaver)
        {
            base.Install(stateSaver);
            string path = this.Context.Parameters["DIR"];
            
            // Do something with path.
        }
    }

实际上，如果您不希望用户更改路径，可以删除对话框直接在用户界面视图中：
