C# and Metadata File Errors
- by j-t-s
Hi All
I've created my own little c# compiler using the tutorial on MSDN, and it's not working properly. I get a few errors, then I fix them, then I get new, different errors, then I fix them, etc etc.
The latest error is really confusing me.
---------------------------
---------------------------
Line number: 0, Error number: CS0006, 'Metadata file 'System.Linq.dll' could not be found;
---------------------------
OK
---------------------------
I do not know what this means.
Can somebody please explain what's going on here?
Here is my code.
MY SAMPLE C# COMPILER CODE:
using System;
namespace JTM
{
public class CSCompiler
{
protected string ot,
rt,
ss, es;
protected bool rg, cg;
public string Compile(String se, String fe, String[] rdas, String[] fs, Boolean rn)
{
System.CodeDom.Compiler.CodeDomProvider CODEPROV = System.CodeDom.Compiler.CodeDomProvider.CreateProvider("CSharp");
ot =
fe;
System.CodeDom.Compiler.CompilerParameters PARAMS = new System.CodeDom.Compiler.CompilerParameters();
// Ensure the compiler generates an EXE file, not a DLL.
PARAMS.GenerateExecutable = true;
PARAMS.OutputAssembly = ot;
foreach (String ay in rdas)
{
if (ay.Contains(".dll"))
PARAMS.ReferencedAssemblies.Add(ay);
else
{
string refd = ay;
refd = refd + ".dll";
PARAMS.ReferencedAssemblies.Add(refd);
}
}
System.CodeDom.Compiler.CompilerResults rs = CODEPROV.CompileAssemblyFromFile(PARAMS, fs);
if (rs.Errors.Count > 0)
{
foreach (System.CodeDom.Compiler.CompilerError COMERR in rs.Errors)
{
es = es +
"Line number: " + COMERR.Line +
", Error number: " + COMERR.ErrorNumber +
", '" + COMERR.ErrorText + ";" +
Environment.NewLine + Environment.NewLine;
}
}
else
{
// Compilation succeeded.
es = "Compilation Succeeded.";
if (rn) System.Diagnostics.Process.Start(ot);
}
return es;
}
}
}
... And here is the app that passes the code to the above class:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string[] f = { "Form1.cs", "Form1.Designer.cs", "Program.cs" };
string[] ra = { "System.dll", "System.Windows.Forms.dll", "System.Data.dll", "System.Drawing.dll", "System.Deployment.dll", "System.Xml.dll", "System.Linq.dll" };
JTS.CSCompiler CSC = new JTS.CSCompiler();
MessageBox.Show(CSC.Compile(
textBox1.Text, @"Test Application.exe", ra, f, false));
}
}
}
So, as you can see, all the using directives are there. I don't know what this error means. Any help at all is much appreciated.
Thank you
