SecureCSharpEval

SecureCSharpEval is a secure and sandboxed C# script execution library that allows users to evaluate C# code dynamically while ensuring safety and preventing malicious activities.

Features

  • Execute C# scripts dynamically with controlled parameters.
  • Prevents unsafe operations such as file access, process execution, and system manipulation.
  • Configurable execution timeout and memory limits.
  • Optimized for .NET – Fully compatible with .NET 6/7/8/9.
  • Optional shell execution support (DISABLED by default for security).

Installation

You can install this library via NuGet Package Manager:

Install-Package SecureCSharpEval

Usage

  • Basic Usage
var eval = new SecureCSharpEval(new CodeValidator(), new ProcessExecutor());
string code = "return x + y;";
var parameters = new Dictionary<string, object>
{
    {"x", 10},
    {"y", 20}
};

object? result = await eval.EvaluateAsync(code, parameters);
Console.WriteLine($"Result: {result}");
  • Using Conditional Statements and Loops
string code = @" 
    int sum = 0;
    for (int i = 0; i < n; i++)
    {
        if (i % 2 == 0)
        {
            sum += i;
        }
    }
    return sum;
";

var parameters = new Dictionary<string, object>
{
    {"n", 10}
};

object? result = await eval.EvaluateAsync(code, parameters);
Console.WriteLine($"Result: {result}");

Configuring Execution Limits

eval.ExecutionTimeoutMs = 3000;  // Increase timeout to 3 seconds
eval.MaxMemoryUsageMb = 100;     // Set max memory usage to 100 MB
eval.AllowShellExecution = true; // Enable shell execution (use with caution)

Security Considerations

  • By default, execution is sandboxed and restricted from running system commands.
  • If enabling AllowShellExecution, ensure proper input validation.
  • Avoid allowing user-provided scripts without proper review.
