i have a dictionary which contain the key as a string and value as the list
so how to get the value od particular key
and i want to replace certatin string from that value which is as a list.

If you mean you have this:
Dictionary<string, List<string>> myDict = ...
then its relatively easy:
List<string> values = myDict["my key"];
values[2] = "new value string";
myDict["my Key"][2] = "new value string";

Sorry? I don't understand you.
Normally you use the dictionary key to find the value: do you want a list of all the keys? Or are you trying to find a key from a value?

If you have a the key, then just use it as in my first example: the key is the string "my key" and it fetches the List of strings associated with the key into the "values" variable.
Try this

Dictionary<string, List<string>> dict = new Dictionary<string, List<string>>();
            dict.Add("one", new string[] { "aaa", "bb", "nnn", "dd" }.ToList());
            dict.Add("two", new string[] { "d", "bb", "cc", "uuu" }.ToList());
            dict.Add("three", new string[] { "affaa", "bb", "cc", "gggdd" }.ToList());
            dict.Add("four", new string[] { "adfdaa", "xxbb", "ccg", "dd" }.ToList());

            string key = "one";
           List<string> Value =  dict[key];
           string replacefrom = "aaa";
           string replaceTo = "apple";
           Value[Value.IndexOf(replacefrom)] = replaceTo;

now the dictionary will be updated with the new item, since it is a reference Type
