C# 从字符串计算

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.

Answer 1

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

You can read more about it here: https://docs.microsoft.com/en-us/dotnet/api/system.data.datatable.compute?view=net-5.0

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

Console.WriteLine(res);
