如何使用字符串动态构建Lambda表达式

using System;
using System.Linq.Expressions;

public class Program
{
    public static void Main()
    {
        string parameterName = "x";
        string expressionString = "x => x > 5";

        // 构建参数表达式
        ParameterExpression parameter = Expression.Parameter(typeof(int), parameterName);

        // 解析字符串构建Lambda表达式
        Expression<Func<int, bool>> lambdaExpression = System.Linq.Dynamic.DynamicExpression.ParseLambda(
            new[] { parameter },
            typeof(bool),
            expressionString
        ) as Expression<Func<int, bool>>;

        // 编译Lambda表达式并执行
        Func<int, bool> func = lambdaExpression.Compile();
        bool result = func(10);

        Console.WriteLine(result);  // 输出：True
    }
}
