I have a textbox1 Text map code

C#

string input = TextBox1.Text;
Dictionary<string, string> map = new Dictionary<string, string>();
map.Add("go", "GYO");
map.Add("oo", "OMO");
map.Add("Go", "OIO");

string temp = input;
foreach (var entry in map)
{
    string key = entry.Key;
    string value = entry.Value;
    temp = Regex.Replace(temp, key, match =>
    {
        bool isUpper = char.IsUpper(match.Value[0]);

        char[] result = value.ToCharArray();
        result[0] = isUpper
            ? char.ToUpper(result[0])
            : char.ToLower(result[0]);
        return new string(result);
    }, RegexOptions.IgnoreCase);

If i type : "go" it replaced to "GYO"
if i type : "oo" it replaced to "OMO"

BUT
IF I type : "Go" it also replaced to "GYO" it cant detect capital word.
when i already mapped "Go" for "OIO" but it shows result "GYO" which i was mapped for small letters "go".

My Question is :
How do i define result different for capital latter and small latter.

thanks in advanced.

Surely the RegexOptions.IgnoreCase; if you want to handle different casings, then you shouldn't tell the regular expression engine not to handle them.
Try RegexOptions.Compiled instead.

Why not:

C#

Dictionary<string, string> map = new Dictionary<string, string>();
map.Add("go", "GYO");
map.Add("oo", "OMO");
map.Add("Go", "OIO");

// usage

string mapItem;

if(map.TryGetValue(TextBox1.Text, out mapItem))
{
    // handle the valid map entry now in 'mapItem
}
else
{
    // handle invalid data in TextBox
}

Opps...bro i got a problem.

If i type : "go" two time in textbox it goes to "else" statement.

but in previous code if i type "gogo"it was did "GYOGYO"
But your code is unable to do this.

could you give me another try kindly ?

However Thanks a lot for your nice try.

while you could have a Dictionary Key 'gogo' mapped to 'GYOGYO' Evidently, what you want is for the user to enter any number of valid "key terms" ... apparently without the need to separate them with some delimiter.

the issue of parsing the text in the TextBox so you can handle multiple entries with cases like "gogo" ... where there's no delimiter separating the terms ... that's a whole other complex task.

I suggest you post another question focused only on that task.

However, if you are the designer here, why not consider creating a custom TextBox that will make it easy for the user to enter only what you wish to allow ? Or, consider, requiring delimiters between each valid "key term" to make it easy to parse the text.

In that question, please make it clear exactly what you wish allow, and dis-allow the user to type in that TextBox.
