MonoDevelop C# - 编译 class 文件时出错

Question

我正在尝试在 MonoDevelop 版本 5.0.1.1 中编译一个基本测试 class。见以下代码：

using System;
using System.IO;
using System.Linq;
using System.Drawing;
using System.Collections;
using System.Collections.Generic;

namespace testproject
{
    public class TestClass
    {
        public TestClass
        {
            string name;
            public string Name
            {
                get {return name;}
                set {name = value;}
            }
            int[] integers;
            public int this[int i]
            {
                get {if (i < 5) {return integers[i];} else {return -1;}}
                set {if (i < 5) {integers[i] = value;}}
            }
            public TestClass(string _name)
            {
                name = _name;
            }
            public override string ToString ()
            {
                string output = name + ":";
                for (int i = 0; i < 5; i++)
                {
                    if (i != 4) {output += " " + i.ToString() + ",";}
                    else {output += " " + i.ToString();}
                }
                return output;
            }
        }
    }
}

这是我创建的一个非常基本的测试 class，用于在 Linux 上试用 MonoDevelop（我刚从 Windows 上的 VS2017 切换过来）。当我尝试编译时，出现以下错误：

/home/main/mono-cs/projects/test-project/test- project/TestClass.cs(3,3): Error CS1519: Invalid token '{' in class, struct, or interface member declaration (CS1519) (test-project)

和

/home/main/mono-cs/projects/test-project/test- project/TestClass.cs(1,1): Error CS1022: Type or namespace definition, or end-of-file expected (CS1022) (test-project)

我仔细检查了一下，所有的花括号都有正确的对应。有什么见解吗？

谢谢大家！

删除public TestClass ,也就是在嵌套中重复添加TestClass
初始化integers否则你会得到一个运行时错误。（感谢@Ron Beyer 提醒）

这里

namespace testproject
{
    public class TestClass
    {
        string name;
        public string Name
        {
            get {return name;}
            set {name = value;}
        }
        int[] integers;
        public int this[int i]
        {
            get {if (i < 5) {return integers[i];} else {return -1;}}
            set {if (i < 5) {integers[i] = value;}}
        }
        public TestClass(string _name)
        {
            name = _name;
            integers = new int[100];
        }
        public override string ToString ()
        {
            string output = name + ":";
            for (int i = 0; i < 5; i++)
            {
                if (i != 4) {output += " " + i.ToString() + ",";}
                else {output += " " + i.ToString();}
            }
            return output;
        }

    }
}
