How Can I Dynamically Execute C# Code from a Text File in a WPF Application?

Dynamically execute code from text file in WPF C# application

WPF C# applications can dynamically execute code from separate text files at runtime. This is useful for situations where code changes frequently or where code needs to be loaded from external resources.

To do this, you can use Microsoft's C# code provider, which allows you to compile and execute code on the fly. Here is a detailed code example:

using System.CodeDom.Compiler;
using System.Reflection;
using System.Text;
using System.IO; // 添加此命名空间用于文件读取

// 从文本文件加载代码
string sourceCode = File.ReadAllText("path/to/your/code.cs"); // 将"path/to/your/code.cs"替换为您的代码文件路径


// 创建C#代码提供程序
CSharpCodeProvider provider = new CSharpCodeProvider();

// 设置编译器参数
CompilerParameters compilerParams = new CompilerParameters
{
    GenerateInMemory = true,
    GenerateExecutable = false,
    ReferencedAssemblies = { "mscorlib.dll", "System.dll", "System.Windows.Forms.dll" } // 添加必要的引用程序集
};

// 编译代码
CompilerResults results = provider.CompileAssemblyFromSource(compilerParams, sourceCode);

// 检查错误
if (results.Errors.Count > 0)
{
    StringBuilder sb = new StringBuilder();
    foreach (CompilerError error in results.Errors)
    {
        sb.AppendLine(error.ToString());
    }
    throw new Exception("编译错误：" + sb.ToString());
}

// 创建已编译代码的实例
object instance = results.CompiledAssembly.CreateInstance("CustomCode.MyCode"); // 假设您的代码定义在CustomCode命名空间下，类名为MyCode

// 调用方法以执行代码
MethodInfo method = instance.GetType().GetMethod("Execute");
if (method != null)
{
    method.Invoke(instance, null);
}
else
{
    throw new Exception("未找到Execute方法。");
}

This example reads the code to be executed from a sourceCode string. Be sure to replace "path/to/your/code.cs" with your actual text file path. Additionally, we added the necessary namespace System.IO and ReferencedAssemblies parameters to ensure the compiler can find the necessary assemblies. Error handling has also been improved to provide more detailed error information.

This approach allows you to dynamically load and execute code from external files, providing flexibility and adaptability in application design. Please note that this approach is a security risk and should only be used on trusted code sources.
