如何通過字符串在Roslyn中創建SyntaxFactory.UsingStatement

Question

我想通過Roslyn填充這種類型的使用語句。

Using(var logger = new MethodLogger("someparam")) 
{ 

} 

我如何產生的呢..

我想這SyntaxFactory.UsingStatement

Answer 1

對於這樣的東西我用roslynquoter。它使用C＃代碼生成roslyn調用。對於你的情況下，它返回是這樣的：

SyntaxFactory 
.UsingStatement(SyntaxFactory.Block()/* the code inside the using block */) 
.WithDeclaration(SyntaxFactory 
    .VariableDeclaration(SyntaxFactory.IdentifierName("var")) 
    .WithVariables(SyntaxFactory.SingletonSeparatedList(SyntaxFactory 
     .VariableDeclarator(SyntaxFactory.Identifier("logger")) 
     .WithInitializer(SyntaxFactory.EqualsValueClause(SyntaxFactory 
      .ObjectCreationExpression(SyntaxFactory.IdentifierName(@"MethodLogger")) 
      .WithArgumentList(/* arguments for MethodLogger ctor */)))
