【问题描述】:
嗨,
我有以下代码:
public static object CreateTypedReport(string typeName, string inheritFrom)
{
DirectoryInfo dirInfo;
CSharpCodeProvider c = new CSharpCodeProvider();
CompilerParameters cp = new CompilerParameters();
foreach (Assembly asm in System.AppDomain.CurrentDomain.GetAssemblies())
{
if(!asm.FullName.StartsWith("ReportAssembly, Version=0.0.0.0"))
cp.ReferencedAssemblies.Add(asm.Location);
}
cp.CompilerOptions = "/t:library";
cp.GenerateInMemory = true;
dirInfo = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\\MyApp\\ReportAssemblies\\");
if (!dirInfo.Exists)
dirInfo.Create();
cp.OutputAssembly = dirInfo.FullName + typeName + "Assembly";
cp.ReferencedAssemblies.Add(typeof(XtraReport).Assembly.Location);
//cp.OutputAssembly = typeName + "Assembly";
StringBuilder sb = new StringBuilder("");
sb.Append("using System;\n");
sb.Append("using MyNamespace.UI;\n");
sb.Append("namespace TypedReports { \n");
sb.Append("public class " + typeName + " : " + inheritFrom + "{ \n");
sb.Append("} \n");
sb.Append("}\n");
CompilerResults cr = c.CompileAssemblyFromSource(cp, sb.ToString());
if (cr.Errors.Count > 0)
{
MessageBox.Show("ERROR: " + cr.Errors[0].ErrorText, "Error evaluating cs code", MessageBoxButtons.OK, MessageBoxIcon.Error);
return null;
}
return cr.CompiledAssembly.CreateInstance("TypedReports." + typeName);
}
这将基于typeName 和inheritFrom 参数创建一个类,然后最终创建并返回一个对象。 inheritFrom 将指向实现IMyInterface 的类。
如果需要,可以将此对象转换为 IMyInterface。
当我们随后序列化和反序列化这个对象时,我们将无法再将其转换为IMyInterface?
为什么?我该如何解决?
