基本结构：

switch (action)
{
    case "list":
        Getcontent();
        break;
    case "day":
        gatherDay();
        break;
    case "all":
        gatherALl();
        break;
    default:
        fire();
        break;
}

 if (!int.TryParse(type, out inttype))
{
      inttype = 0;
 }

stringBuilder sb=new stringBuilder();
for(int i=0;i<10;i++;)
{
     sb.append("a"+i.tosrtring());
}

数组操作：

        // Declare a single-dimensional array 
        int[] array1 = new int[5];

        // Declare and set array element values
        int[] array2 = new int[] { 1, 3, 5, 7, 9 };

        // Alternative syntax
        int[] array3 = { 1, 2, 3, 4, 5, 6 };

        // Declare a two dimensional array
        int[,] multiDimensionalArray1 = new int[2, 3];

        // Declare and set array element values
        int[,] multiDimensionalArray2 = { { 1, 2, 3 }, { 4, 5, 6 } };

        // Declare a jagged array
        int[][] jaggedArray = new int[6][];

        // Set the values of the first array in the jagged array structure
        jaggedArray[0] = new int[4] { 1, 2, 3, 4 };
