动态参数的方法 [英] method with dynamic parameters

问题描述

我想创建一个可以这样调用的过程:

I want to create a procedure I could call like this:

extraString myObject = new extraString();<br />
string myString = "The file %1 cannot be deleted with the current user %2. The file %1 is blocked by another user, please try again later";<br />
myObject.StrBuild(myString, "test.txt", "John Citizen");

对于此过程，我想传递尽可能多的参数，以在我的原始字符串中替换％+ [increment number].

像这样的东西:

For this procedure I want to pass as many parameters as I want, to replace in my original string the % + [increment number].

Something like this:

    class extraString<br />
    {<br />
        public string StrBuild(string stringToBuild, string param1)<br />
        {<br />
            StringBuilder objBuilder = new StringBuilder(stringToBuild);<br />
            objBuilder.Replace("%1", param1);<br />
            return objBuilder.ToString();<br />
        }<br />
        public string Strbuild(string stringToBuild, string param1, string param2)<br />
        {<br />
            StringBuilder objBuilder = new StringBuilder(stringToBuild);<br />
            objBuilder.Replace("%1", param1);<br />
            objBuilder.Replace("%2", param2);<br />
            return objBuilder.ToString();<br />
        }<br />
... <br />
        public string Strbuild(string stringToBuild, string param1, string param2, ..., string param20)<br />
        {<br />
            StringBuilder objBuilder = new StringBuilder(stringToBuild);<br />
            objBuilder.Replace("%1", param1);<br />
            objBuilder.Replace("%2", param2);<br />
            ...<br />
objBuilder.Replace("%20", param20);<br />
            // return the constructed string<br />
            return objBuilder.ToString();<br />
        }<br />
    }

如何在不每次都具有一个或多个参数的情况下编写20种相同方法的情况下实现它.

预先谢谢您.

How can I realize it without writing the 20 same methods with each time one or more parameter.

Thank you in advance.

推荐答案

您可以使用任意多个参数.

You can use as many parameters as you want to.

class Program
{
    static void Main(string[] args)
    {
        ExtraString myObject = new ExtraString();
        string myString = @"The file %1 cannot be deleted with the current user %2. The file %1 is blocked by another user, please try again later";
        Console.WriteLine(myObject.StrBuild(myString, new string[]{"test.txt", "John Citizen"}));
    }
}

class ExtraString
{
    public string StrBuild(string stringToBuild, string[] parameters)
    {
        StringBuilder objBuilder = new StringBuilder(stringToBuild);
        for (int i=0;i<parameters.Length;i++)
        {
            objBuilder.Replace(@"%"+(i+1).ToString(), parameters[i]);
        }
        return objBuilder.ToString();
    }
}
