How Can I Achieve Dynamic Code Execution in C# Like JavaScript's eval()?

The dynamic code in the c#executes

Similar to the

function in JavaScript, C#can use the Roslyn script API to implement the dynamic code. This API allows you to dynamically compile and execute the C#code at runtime.

eval() Example:

Suppose you have an integer variable and multiple attributes such as "Property1", "Property2", "Property3". You want to perform operations on the "Property

I

" attribute according to the i value. i Solution using the Roslyn script API:

This example dynamically loads the assembly and access the attribute according to the value.

// 添加NuGet包 'Microsoft.CodeAnalysis.Scripting'
using Microsoft.CodeAnalysis.CSharp.Scripting;

await CSharpScript.EvaluateAsync($"System.Reflection.Assembly.LoadFrom(\"{new FileInfo(\"your-assembly-to-load.dll\").FullName}\")");

await CSharpScript.RunAsync($"var propertyValue = typeof(YourType).GetProperty(\"Property{i}\").GetValue(yourTypeInstance);");

Other functions:

Roslyn script API allows you to execute any C#code fragment:
