这是我的代码示例
using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using Microsoft.CodeAnalysis.Text;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace RoslynTest
{
class Program
{
static void Main(string[] args)
{
myClass obj = new myClass();
obj.Exec();
}
}
public class myClass
{
private string _path;
private readonly IEnumerable<MetadataReference> DefaultReferences =
new[]
{
MetadataReference.CreateFromFile(@"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6\mscorlib.dll"),
MetadataReference.CreateFromFile(@"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6\System.dll"),
MetadataReference.CreateFromFile(@"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6\System.Core.dll")
};
private readonly CSharpCompilationOptions DefaultCompilationOptions =
new CSharpCompilationOptions(OutputKind.DynamicallyLinkedLibrary)
.WithOverflowChecks(true).WithOptimizationLevel(OptimizationLevel.Release)
.WithUsings(new[]
{
"System",
"System.Collections.Generic"
});
private SyntaxTree Parse(string text, string filename = "", CSharpParseOptions options = null)
{
var stringText = SourceText.From(text, Encoding.UTF8);
return SyntaxFactory.ParseSyntaxTree(stringText, options, filename);
}
private string source = "public class Test1 { public int Amount {get; set;} public void CalcAmo() { Amount = Amount + 500;} public void CalcAmo1() { Amount = Amount + 1000; } } ";
public void Exec()
{
var parsedSyntaxTree = Parse(source, "", CSharpParseOptions.Default.WithLanguageVersion(LanguageVersion.CSharp6));
var compilation = CSharpCompilation.Create(
"Compilation",
syntaxTrees: new SyntaxTree[] { parsedSyntaxTree },
references: DefaultReferences,
options: DefaultCompilationOptions);
_path = "C:\\custom.dll";
var result = compilation.Emit(_path);
if (!result.Success)
{
foreach (var item in result.Diagnostics)
{
Console.WriteLine(item.ToString());
}
}
Console.ReadLine();
}
}
}
我正在通过输入字符串创建编译,然后从诊断中获取编译错误,但这还不够
我想知道关于编译错误的一切。
在此代码中没有任何编译错误,但如果有,我将获得有关错误的详细信息,例如,如果我将删除一些&#39; ; &#39 ;从输入字符串我将得到&#34; ;预期&#34; ,但它没有实现。我会得到详细信息,例如哪一行出现此错误?
它有可能吗?请帮帮我。感谢advacie
