C# calculate from string

Question

I trying to calculate my string but I don't have any idea how to do that.

I want to do something like this:

string input = "2+2+2+2*5^2/2";
Console.WriteLine(Calculate(input));

I tried to use DataTable().Compute() but its dose not support many of operators.

Does this answer your question?

You can use DataTable.Compute for that. this method computes the given expression on the current rows that pass the filter criteria.

string input = "2+2+2+2*5^2/2";
string res = new DataTable().Compute(input, null).ToString();

Console.WriteLine(res);
