I have function as below .

public static object getClassInstance(string key, object constructorParameter)
{
         // body here
}

Key variable will have my class name . I need to return the new instance of the class . If the constructorParm is null then i need to load the class with default constructor else with the constructor parameter passed. How do i do this ?

ADD :

I wrote the code like this

public static object getClassInstance(string key, params object[] constructorArgs) { string assemblyPath = null; string customClassName = key.Substring(0, 1) + "Custom" + key.Substring(1);

        DataSet objDataset = getAssemblyInfo(key);
        if (objDataset != null && objDataset.Tables.Count > 0 && objDataset.Tables[0].Rows.Count > 0)
        {
            assemblyPath = objDataset.Tables[0].Rows[0]["ACA_ASSEMBLY_PATH"].ToString();
        }

        Assembly assembly;
        Type type;

        if (assemblyPath != null && assemblyPath != string.Empty)
        {
            assembly = Assembly.LoadFile(assemblyPath);
            type = assembly.GetType(customClassName);
        }
        else // if no customisation
        {
            type = Type.GetType(key);
        }

        object classInstance = constructorArgs == null ? Activator.CreateInstance(type) : Activator.CreateInstance(type, constructorArgs);
        if (classInstance == null) throw new Exception("broke");
        return classInstance;

    }

key passed to the function is "CReportBO". CReportBO is accessible in the function's scope . but in //if no customization section (i.e type = Type.GetType(key) ) , type returns me null . whats wrong ?
