method with dynamic parameters

Question

5.00/5 (1 vote)

See more:

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");

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 />
    }

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

Thank you in advance.

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();
    }
}
