删除 Codedom 生成的代码中的项目

有没有办法从 VB 代码中删除 Codedom 中生成的代码中的项目？

例如，在我生成的所有代码的顶部，它有：

'------------------------------------------------------------------------------
' 
'     This code was generated by a tool.
'     Runtime Version:4.0.30319.1
'
'     Changes to this file may cause incorrect behavior and will be lost if
'     the code is regenerated.
' 
'------------------------------------------------------------------------------
Option Strict Off 
Option Explicit On

我希望这两个都消失 - 注释文本和 Option xxx。我尝试过使用 CodeGeneratorOptions，但无法从生成的代码中删除上述内容。

原文

Is there a way to remove items in code generated in Codedom from VB code?

For example at the top of all the code I generate, it has:

'------------------------------------------------------------------------------
' 
'     This code was generated by a tool.
'     Runtime Version:4.0.30319.1
'
'     Changes to this file may cause incorrect behavior and will be lost if
'     the code is regenerated.
' 
'------------------------------------------------------------------------------
Option Strict Off 
Option Explicit On

I'd like both of these to go away - the commented text and the both the Option xxx. I've tried toying around with CodeGeneratorOptions, but have not been able to remove the above from generated code.

对于＃2，你尝试过这个吗？

CodeCompileUnit.UserData.Add("AllowLateBound", False) ' strict on
CodeCompileUnit.UserData.Add("RequireVariableDeclaration", False) ' explicit off

（其中 CodeCompileUnit 是 CodeCompileUnit 类型的变量）

For #2, have you tried this?

CodeCompileUnit.UserData.Add("AllowLateBound", False) ' strict on
CodeCompileUnit.UserData.Add("RequireVariableDeclaration", False) ' explicit off

(where CodeCompileUnit is a variable of type CodeCompileUnit)

您可以使用 StringWriter 输出代码，然后使用 StringBuilder.Remove 删除第一行：

using (var stringWriter = new StringWriter())
using (var streamWriter = new StreamWriter(path))
{
    codeDomProvider.GenerateCodeFromCompileUnit(unit, stringWriter, options);
    StringBuilder sb = stringWriter.GetStringBuilder();
    /* Remove the header comment (444 is for C#, use 435 for VB) */
    sb.Remove(0, 444);
    streamWriter.Write(sb);
}

它很难看，但它有效™

You can use a StringWriter to output your code, then use StringBuilder.Remove in order to delete the first lines:

using (var stringWriter = new StringWriter())
using (var streamWriter = new StreamWriter(path))
{
    codeDomProvider.GenerateCodeFromCompileUnit(unit, stringWriter, options);
    StringBuilder sb = stringWriter.GetStringBuilder();
    /* Remove the header comment (444 is for C#, use 435 for VB) */
    sb.Remove(0, 444);
    streamWriter.Write(sb);
}

It's ugly, but it works ™

不，那是无法删除的。它被硬编码到 VBCompiler 中。您可以在 Reflector 的 system.dll 中看到这一点。

这是我的提案，灵感来自 Maxence 的提案，但可能有点“干净”，因为我使用正则表达式而不是可能随时间变化的索引。这应该适用于 C# 和 VB.net。

using (var stringWriter = new StringWriter())
using (var sourceWriter = new StreamWriter(fileName, false, Encoding.UTF8))
{
   codeDomProvider.GenerateCodeFromCompileUnit(CodeUnit, stringWriter, generatorOptions);
   var newContent = Regex.Replace(stringWriter.ToString(), @"^//.*Runtime Version:.*$", "//\r", RegexOptions.Multiline);
   sourceWriter.Write(newContent);
}

Here is my proposal inspired from Maxence's one, but maybe a bit "cleaner", as I'm using a regular expression instead of indexes that may vary over time. This should work for both C# and VB.net.

using (var stringWriter = new StringWriter())
using (var sourceWriter = new StreamWriter(fileName, false, Encoding.UTF8))
{
   codeDomProvider.GenerateCodeFromCompileUnit(CodeUnit, stringWriter, generatorOptions);
   var newContent = Regex.Replace(stringWriter.ToString(), @"^//.*Runtime Version:.*quot;, "//\r", RegexOptions.Multiline);
   sourceWriter.Write(newContent);
}
