This article mainly introduces "what is the application method of compiling C # code". In the daily operation, I believe that many people have doubts about the application method of compiling C # code. I have consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubt of "what is the application method of compiling C # code?" Next, please follow the editor to study!

Compile C# code application scenarios:

I haven't figured out where it will be used. Who writes the dynamic code? I think there are some difficulties for ordinary users. Especially with dynamic embedded scripts like IronPython that are easier to use.

1) Auxiliary development tools like LINQPad

2) implement script engine?

3) discuss.

Mainly use the namespace Microsoft.CSharp to compile the C # code, and then use CodeDom and reflection calls. I've written a test tool here. Look at the code:

Using System

Using System.Collections.Generic

Using System.ComponentModel

Using System.Drawing

Using System.Windows.Forms

Using System.CodeDom.Compiler

Using Microsoft.CSharp; / / is used to compile C # code

Using System.Reflection; / / for reflection calls

Namespace CodeDomLearn

{

Public partial class Form1: Form

{

Public Form1 () {

InitializeComponent ()

}

Private void button1_Click (object sender, EventArgs e) {

CodeCompiler.Compile (new string [] {}, textBox1.Text, "")

ListBox1.Items.Clear ()

Foreach (string s in CodeCompiler.ErrorMessage) {

ListBox1.Items.Add (s)

}

ListBox1.Items.Add (CodeCompiler.Message)

}

}

Static class CodeCompiler {

Static public string Message

Static public List ErrorMessage = new List ()

Public static bool Compile

(string [] references, string source, string outputfile) {

/ / compilation parameters

CompilerParameters param = new CompilerParameters

(references, outputfile, true)

Param.TreatWarningsAsErrors = false

Param.GenerateExecutable = false

Param.IncludeDebugInformation = true

/ / compile

CSharpCodeProvider provider = new CSharpCodeProvider ()

CompilerResults result = provider.CompileAssemblyFromSource

(param, new string [] {source})

Message = ""

ErrorMessage.Clear ()

If (! result.Errors.HasErrors) {/ / reflection call

Type t = result.CompiledAssembly.GetType ("MyClass")

If (t! = null) {

Object o = result.CompiledAssembly.CreateInstance ("MyClass")

Message = (string) t.InvokeMember ("GetResult", BindingFlags.Instance |

BindingFlags.InvokeMethod | BindingFlags.Public, null, o, null)

}

Return true

}

Foreach (CompilerError error in result.Errors) {/ / lists compilation errors

If (error.IsWarning) continue

ErrorMessage.Add ("Error (" + error.ErrorNumber + ") -" + error.ErrorText + "

"\ t\ tLine:" + error.Line.ToString () + "Column:" + error.Column.ToString ())

}

Return false

}

}

}

As a demonstration, the example simply states that the class name must be MyClass and that there must be a method that returns a GetResult method of type string.

At this point, the study on "what is the application method of compiling C # code" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
