how to split a string using c#

Assuming your text would have exactly one tilde and equal sign, you may try the following string split:

string input = "DEV~Hi there is Sunday Tommorrow=1";
var match = Regex.Split(input, @"[~=]")[1];
Console.WriteLine(match); // Hi there is Sunday Tommorrow

Another approach, perhaps a bit more robust, would be to use a regex replacement:

string input = "DEV~Hi there is Sunday Tommorrow=1";
string match = Regex.Replace(input, @"^.*~(.*)=.*$", "1ドル");
Console.WriteLine(match); // Hi there is Sunday Tommorrow

You are trying to match a specific pattern. You need a regular expression for this. The expression ~.*= will match everything between ~ and =, including the characters:

~Hi there is Sunday Tommorrow=

To avoid capturing these characters you can use (?<=~).*(?==). The call Regex.Match(myString,"(?<=~).*(?==)") will catch just the part between the markers :

var match=Regex.Match(myString,"(?<=~).*(?==)");
Console.WriteLine(match);
-------------------------------
Hi there is Sunday Tommorrow

These are called look-around assertions. The first one, (?<=~) says that the match is precededed by ~ but the marker isn't included. The second one, (?==) says that the match is followed by = but again, the marker isn't included.

Another possibility is to use a group to capture the part(s) you want by using parentheses:

var m=Regex.Match(s,"~(.*)="); 
Console.WriteLine(m.Groups[1]);
---------------------------------
Hi there is Sunday Tommorrow

You can use more than one group in a pattern

The proper way to do this is using RegEx, But a smiple soloution for this case:

obj.Code.Trim().Split('~')[1].Split('=')[0].Trim()

Try the below code:

obj.Code.Trim().Split('=')[0].Trim().Split('~')[1]
