Question

想要分享我发现从程序集名称中删除强名称的方法。我用它来进行序列化，但我认为它也可以用于其他事情。

    private Regex _assemRegex = new Regex("(?<assembly>^.*?),.*");
    Regex reg = new Regex("(?<type>.*?), PublicKeyToken(=.*?)](?<end>.*)");
    //assume that all replacement types are in the same assembly with TypeReplacer
    static readonly string assembly2Use = System.Reflection.Assembly.GetExecutingAssembly().FullName;

    public override Type BindToType(string assemblyName, string typeName)
    {
        // remove strong name from assembly
        Match match = _assemRegex.Match(assemblyName);
        if (match.Success)
        {
            assemblyName = match.Groups["assembly"].Value;
        }

        // remove strong name from any generic collections as many time as needed
        match = reg.Match(typeName);
        string typeWithoutSN = typeName;
        while (match.Success)
        {
            typeWithoutSN = string.Format("{0}]{1}",
            match.Groups["type"].Value,
            match.Groups["end"].Value);
            match = reg.Match(typeWithoutSN);
        }

        // replace assembly name with the simple assembly
        // name - strip the strong name
        string type = string.Format("{0}, {1}", typeWithoutSN,
        assemblyName);

        // The following line of code returns the type.
        return Type.GetType(type);
    }

根据要求，代码标记为答案：

private Regex _assemRegex = new Regex("(?<assembly>^.*?),.*");
Regex reg = new Regex("(?<type>.*?), PublicKeyToken(=.*?)](?<end>.*)");
//assume that all replacement types are in the same assembly with TypeReplacer
static readonly string assembly2Use = System.Reflection.Assembly.GetExecutingAssembly().FullName;

public override Type BindToType(string assemblyName, string typeName)
{
    // remove strong name from assembly
    Match match = _assemRegex.Match(assemblyName);
    if (match.Success)
    {
        assemblyName = match.Groups["assembly"].Value;
    }

    // remove strong name from any generic collections as many time as needed
    match = reg.Match(typeName);
    string typeWithoutSN = typeName;
    while (match.Success)
    {
        typeWithoutSN = string.Format("{0}]{1}",
        match.Groups["type"].Value,
        match.Groups["end"].Value);
        match = reg.Match(typeWithoutSN);
    }

    // replace assembly name with the simple assembly
    // name - strip the strong name
    string type = string.Format("{0}, {1}", typeWithoutSN,
    assemblyName);

    // The following line of code returns the type.
    return Type.GetType(type);
}

使用正则表达式进行序列化时，从程序集中删除强名称
