WIX自定义操作参数中的连接字符串 [英] Connection String in a WIX Custom Action Parameter

问题描述

使用WIX 3.7，我想将连接字符串传递到自定义操作中。但是，由于连接字符串包含;，因此自定义操作数据无法正确解析。

Using WIX 3.7, I want to pass a connection string into a custom action. However, since the connection string contains ';' the custom action data is not being parsed correctly.

<CustomAction Id="PopulateActionPrep" Property="PopulateAction" Execute="immediate" Value="CONNECTIONSTRING=&quot;[CONNECTIONSTRING]&quot;;PRODUCTVERSION=[ProductVersion]" /> 

我尝试使用引号对连接字符串进行转义，但这没有用。当我从CustomActionData中读取 CONNECTIONSTRING 属性时，它会返回 Data Source = SqlServerName 。

I tried using quotes to escape the connection string but that did not work. When I read the CONNECTIONSTRING property from CustomActionData it comes back with "Data Source=SqlServerName.

如何在WIX中转义等分号？

Is there a way to escape equal semicolons in WIX?

推荐答案

答案是是，您转义了; 使用 ;; ：

The answer is yes, you escape ; using ;;:

/// <summary>
/// Escapes a value string by doubling any data-separator (semicolon) characters.
/// </summary>
/// <param name="value"></param>
/// <returns>Escaped value string</returns>
private static string Escape(string value)
{
    value = value.Replace(String.Empty + CustomActionData.DataSeparator, String.Empty + CustomActionData.DataSeparator + CustomActionData.DataSeparator);
    return value;
}

可能甚至更好的消息，您可以将数据作为原始字符串访问并完全控制其反序列化的方式：

Potentially even better news, you can access the data as a raw string and be in total control of how it is deserialized:

var rawString = session["CustomActionData"];

这就是 Session.CustomActionData 的全部

/// <summary>
/// Gets custom action data for the session that was supplied by the caller.
/// </summary>
/// <seealso cref="DoAction(string,CustomActionData)"/>
public CustomActionData CustomActionData
{
    get
    {
        if (this.customActionData == null)
        {
            this.customActionData = new CustomActionData(this[CustomActionData.PropertyName]);
        }


        return this.customActionData;
    }
}
