Compare two strings and combine into a string.

[Janice Hui]

Hi,

I have two strings as below:

string a = "A, 0001; B, 0002; C, 0003;";
string b = "0001, From, FlowA; 0002, To, FlowB; 0003, From, FlowC; 0003, To, FlowD;";
 

I would like to produce a new string c with the output:

A, From, FlowA; B, To, FlowB; C, From, FlowC; C, To, FlowD;

Is that anyway for me to do it?
Thank.

You can use String.Split to split each source string into string arrays
Then merge together whatever parts you want.

Looks like after you use String.Split twice, just use String.Replace with the items of the string arrays as arguments.

You would have to apply a combination of string.split and string.replace to accomplish that.

Hi harrisunderwork,

Thank for your answer. Based on your answer, i should apply the string.replace in combination of string. However, string.replace is used to replace certain word in a sentences. In my case, i would like to combine this two string and at the same the similar word is needed to eliminate. Does string.replace can make it?

Now, i'am using the foreach and array method together in order to get the output. Thank.

Yes, you would do something like:

b = b.Replace("A", "0001");
except "A" and "0001" would be variables which are set when you tokenize the string.
