[C#] 透過繼承抽象類別(泛型)並實作
public abstract class Shape<S,T>
{
T _Result=default(T);
S _ShapeName = default(S);
//Calculate Shape Area
public virtual T Area(T Par1, T Par2) { return _Result; }
//Calculate Shape Volume
public virtual T Volume(T Length, T Width, T Height) { return _Result; }
//Calculate Triangle Volume
public virtual T Volume(T Bottom, T Height) { return _Result; }
//Show Is ShapeName
public virtual S ShapeName() { return _ShapeName; }

[C#] 利用LIQN 實作 兩個DataTable 差集
private DataTable _dt1 ;
private DataTable _dt2;
public Form1()
{
InitializeComponent();
_dt1 = new DataTable();
_dt2 = new DataTable();
}
private void Form1_Load(object sender, EventArgs e)
{
_dt1.Columns.Add(new DataColumn("Root", typeof(string)));
DataRow r;
for (int i = 1; i < 6; i++)
{
r = _dt1.NewRow();
r["Root"] = i;
_dt1.Rows.Add(r);
}
_dt2.Columns.Add(new DataColumn("Root", typeof(string)));
for (int i = 1; i < 11; i++)
{
r = _dt2.NewRow();
r["Root"] = i;
_dt2.Rows.Add(r);
}
}
private void btnAction_Click(object sender, EventArgs e)
{
IEnumerable<DataRow> Query1 = _dt1.AsEnumerable();
IEnumerable<DataRow> Query2 = _dt2.AsEnumerable();
DataTable dt = Query2.Except(Query1, DataRowComparer.Default).CopyToDataTable();
dataGridView1.DataSource = dt;
}
結果如下:
private DataTable _dt2;
public Form1()

_dt1 = new DataTable();
_dt2 = new DataTable();

[C#]利用除法原理讀取矩陣(二維陣列)
程式碼如下:
private void Result(int[,] Result)
{
int ResultRows = 0, ResultCols = 0;
ResultRows = Result.GetLength(0);
ResultCols = Result.GetLength(1);
int k = ResultRows * ResultCols;
int x=0,y=0;
string result = "";
for (int i = 0; i < k; i++)
{
//i:被除數 ResultCols:除數
x = i / ResultCols;//商數
y = (i - (x * ResultCols));//餘數
if (y == (ResultCols -1))
{
result += Result[x, y] + "\n";
} else {
result += Result[x, y] + " ";
}
}
MessageBox.Show(result);
}
