c# - "' 表格1 ' already defines a member called ' .ctor ' with the same parameter types "

Question

我有这段代码，它将语音转换为文本并将其打印在 Windows 表单的列表框中，但是当我尝试在 Visual Studio 2017 中编译它时，它不会编译，因为错误“'Form1'已经定义了一个名为 '.ctor' 的成员' 具有相同的参数类型 ".

逻辑如下:

Program.cs

using System;
using System.Data;
using System.Drawing;
using System.Windows.Forms;
using Microsoft.Speech.Recognition;
using System.Globalization;
namespace WinFormSpeech
{
    public partial class Form1 : Form
    {
        static CultureInfo ci = new CultureInfo("en-IN");
        static SpeechRecognitionEngine sre =
          new SpeechRecognitionEngine(ci);
        public Form1()
        {

            InitializeComponent();
            sre.SetInputToDefaultAudioDevice();
            sre.SpeechRecognized += sre_SpeechRecognized;
            Grammar g_HelloGoodbye = GetHelloGoodbyeGrammar();
            Grammar g_SetTextBox = GetTextBox1TextGrammar();
            sre.LoadGrammarAsync(g_HelloGoodbye);
            sre.LoadGrammarAsync(g_SetTextBox);
            // sre.RecognizeAsync() is in CheckBox event
        }
        static Grammar GetHelloGoodbyeGrammar()
        {
            Choices ch_HelloGoodbye = new Choices();
            ch_HelloGoodbye.Add("hello");
            ch_HelloGoodbye.Add("goodbye");
            GrammarBuilder gb_result =
              new GrammarBuilder(ch_HelloGoodbye);
            Grammar g_result = new Grammar(gb_result);
            return g_result;
        }
        static Grammar GetTextBox1TextGrammar()
        {
            Choices ch_Colors = new Choices();
            ch_Colors.Add(new string[] { "red", "white", "blue" });
            GrammarBuilder gb_result = new GrammarBuilder();
            gb_result.Append("set text box 1");
            gb_result.Append(ch_Colors);
            Grammar gi_result = new Grammar(gb_result);
            return gi_result;
        }
        private void checkBox1_CheckedChanged(object sender,
          EventArgs e)
        {
            if (checkBox1.Checked == true)
                sre.RecognizeAsync(RecognizeMode.Multiple);
            else if (checkBox1.Checked == false) // Turn off
                sre.RecognizeAsyncCancel();
        }
        void sre_SpeechRecognized(object sender,
          SpeechRecognizedEventArgs e)
        {
            string txt = e.Result.Text;
            float conf = e.Result.Confidence;
            if (conf < 0.65) return;
            this.Invoke(new MethodInvoker(() =>
            {
                listBox1.Items.Add("I heard you say: "
              + txt);
            })); // WinForm specific
            if (txt.IndexOf("text") >= 0 && txt.IndexOf("box") >=
              0 && txt.IndexOf("1") >= 0)
            {
                string[] words = txt.Split(' ');
                this.Invoke(new MethodInvoker(() =>
                { textBox1.Text = words[4]; })); // WinForm specific
            }
        }
    } // Form
} // ns

这是设计器代码:

Form1.Designer.cs

namespace WinFormSpeech

    partial class Form1
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>

        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

你知道如何解决这个问题吗？

尝试将您的类重命名为 Form1 以外的名称。如果同一文件夹或命名空间中有多个同名的类，有时 Visual Studio 可能会感到困惑。
