使用Roslyn獲取SqlCommand本地var聲明

Question

我正在嘗試從方法主體中獲取第一個SqlCommand本地聲明。

這是我的代碼方法聲明訪問者：

public override void VisitMethodDeclaration(MethodDeclarationSyntax node)
{
    var sqlCommandDeclaration = node.Body.Statements
            .Where(x => x.IsKind(LocalDeclarationStatement))
            .Cast<LocalDeclarationStatementSyntax>()
            .FirstOrDefault(x => x.Declaration.Type.GetText().ToString() == "SqlCommand");

    base.VisitMethodDeclaration(node);
}

有人可以幫我嗎？

Answer 1

    var firstOne = node.Body.Statements
        .OfType<LocalDeclarationStatementSyntax>()
        .FirstOrDefault(syntax => syntax.Declaration.Type.ToString() == "SqlCommand");
