Question

我有一个文本文件，上面有两个表，就像这样

1:"Transmitter",1,grid,32,6 

2:"Parameters", 2,list,64

我想在表单中显示两个表，如果需要，用户可以在文本文件中添加更多表。如果用户向表单添加更多表，则表单中将显示其他表。

我正在使用制表符控件将标签添加到从文件指定的表单中，对于我正在使用数据网格视图的表格

这是我的代码：

public partial class Form1 : Form
    {
        String line;
        String typeOfTable;
        int amountOfRows;
        int amountOfColumns;

        private const String TABS = "TABS";
        private const String TABLES = "TABLES";
        private const String GRID = "grid";
        private const String LIST = "list";

        private const int LOCATION_TABLE_TYPE = 2;
        private const int LOCATION_TABLE_AMOUNT_ROWS = 3;
        private const int LOCATION_TABLE_AMOUNT_COLUMNS = 4;
        private const int AMOUNT_Columns_IN_LIST = 2;


        String[] splitTableArray;

        public Form1()
        {
            InitializeComponent();
            getFormContentFromFile();
        }

        private void getFormContentFromFile()
        {
            using (StreamReader reader = new StreamReader("neo2G.res"))
            {
                while (!reader.EndOfStream)
                {
                    line = reader.ReadLine();

                    if (line.Equals(TABS))
                    {
                        while (!line.Equals(".."))
                        {
                            line = reader.ReadLine();

                            if (!line.Equals(".."))
                            {
                                createTabInForm(line);

                            }

                        }
                    }

                    if (line.Equals(TABLES))
                    {
                        while (!line.Equals(".."))
                        {
                            line = reader.ReadLine();

                            if (!line.Equals(".."))
                            {
                                splitTableLineToArray(line);
                                typeOfTable = splitTableArray[LOCATION_TABLE_TYPE];
                                amountOfRows = int.Parse(splitTableArray[LOCATION_TABLE_AMOUNT_ROWS]);

                                if(typeOfTable.Equals(GRID))
                                {
                                    amountOfColumns = int.Parse(splitTableArray[LOCATION_TABLE_AMOUNT_COLUMNS]);

                                }

                                else if( typeOfTable.Equals(LIST))
                                {
                                    dataGridView1.DataSource = createListForForm(amountOfRows);

使用设计器添加一个或（更好）两个表。

分析设计人员添加的代码，并将其作为从代码中添加表格的起点。

从文本文件C＃添加表到表单
