评估字符串“3*(4+2)"产量 int 18

Evaluating string quot;3*(4+2)quot; yield int 18(评估字符串“3*(4+2)产量 int 18)

问题描述

Is there a function the .NET framework that can evaluate a numeric expression contained in a string and return the result? F.e.:

string mystring = "3*(2+4)";
int result = EvaluateExpression(mystring);
Console.Writeln(result); // Outputs 18

Is there a standard framework function that you can replace my EvaluateExpression method with?

If you want to evaluate a string expression use the below code snippet.

using System.Data;

DataTable dt = new DataTable();
var v = dt.Compute("3 * (2+4)","");
