Hello there!
This article will help us to develop code which could basically compile our code. This could help us in creating web/ windows based C# compiler even TTD as well. Enjoy the code.
using System;
using System.CodeDom.Compiler;
using System.Collections.Generic;
namespace WebSharpCompilerBusiness
{
public class WebSharpCompiler
{
public List<string> Compile(string programText)
{
List<string> messages = new List<string>();
if
(String.IsNullOrEmpty(programText))
{
messages.Add("program text cannot
be null or empty");
}
CompilerResults compilerResults = ProcessCompilation(programText);
foreach (CompilerError error in compilerResults.Errors)
{
messages.Add(String.Format("Line {0} Error No:{1}
- {2}", error.Line,
error.ErrorNumber, error.ErrorText));
}
return messages;
}
public CompilerResults ProcessCompilation(string programText)
{
CodeDomProvider codeDomProvider = CodeDomProvider.CreateProvider("CSharp");
System.CodeDom.Compiler.CompilerParameters parameters = new CompilerParameters();
parameters.GenerateExecutable = false;
return codeDomProvider.CompileAssemblyFromSource(parameters, programText);
}
}
}
Now, for demo purpose I am simply demonstrating an UnitTest over here.
[TestMethod]
public void TestCompilerSingleError()
{
WebSharpCompiler compiler = new
WebSharpCompiler();
string programText = @"
using System;
namespace HelloWorld
{
class HelloWorldClass
{
static void Main(string[]
args)
{
// byte c = 1/0;
Console.ReadLine();
}
}
}";
List<string> compilerErrors =
compiler.Compile(programText);
Assert.AreEqual(compilerErrors.Count, 0);
}
That's all!
Cheers!
