Class with custom Constraint

问题

以下是您要翻译的代码部分：

  1. class Matrix<T> where T :  /*已定义为所有加法、乘法和减法操作*/
  2. {
  3.     public List<List<T>> Lines { get; set; }
  4.     public Matrix()
  5.     {
  6.         Lines = new List<List<T>>();
  7.     }
  8.     public T this[int line, int column]
  9.     {
  10.         get => Lines
    [column];
  11.         set => Lines
    [column] = value;
  12.     }
  13.     public List<T> this[int line]
  14.     {
  15.         get => Lines
    ;
  16.     }
  17.     private static T LineMultiplyCol(List<T> l, List<T> c)
  18.     {
  19.         T index = default;
  20.         for (int i = 0; i < l.Count; i++)
  21.         {
  22.             index += l[i] * c[i]; //这里是错误的地方。
  23.         }
  24.         return index;
  25.     }
  26.     public static Matrix<T> operator *(Matrix<T> m1, Matrix<T> m2)
  27.     {
  28.         //我想要完成这个部分。
  29.     }
  30. }

请注意，我只翻译了您提供的代码部分，而不包括其他内容。

How can I do this? Limit to use defined operation Data Types(T) or
limit to use an T whit Defined for all addition, multiplication and subtraction operations here is my Matrix class

  1. class Matrix&lt;T&gt; where T :  /*Defined for all addition, multiplication and subtraction operations*/
  2. {
  3.     public List&lt;List&lt;T&gt;&gt; Lines { get; set; }
  4.     public Matrix()
  5.     {
  6.         Lines = new List&lt;List&lt;T&gt;&gt;();
  7.     }
  8.     public T this[int line, int column]
  9.     {
  10.         get =&gt; Lines
    [column];
  11.         set =&gt; Lines
    [column] = value;
  12.     }
  13.     public List&lt;T&gt; this[int line]
  14.     {
  15.         get =&gt; Lines
    ;
  16.     }
  17.     private static T LineMultiplyCol(List&lt;T&gt; l, List&lt;T&gt; c)
  18.     {
  19.         T index = default;
  20.         for (int i = 0; i &lt; l.Count; i++)
  21.         {
  22.             index += l[i] * c[i]; //Here is the error.
  23.         }
  24.         return index;
  25.     }
  26.     public static Matrix&lt;T&gt; operator *(Matrix&lt;T&gt; m1, Matrix&lt;T&gt; m2)
  27.     {
  28.         //i want to complete this.
  29.     }
  30. }

this is my program, i want to expend to Parametric Matrix Operations, and need to do it

Parametric Matrix Operations and etc.

得分: 2

.NET 7/C#11引入了新的通用数学。您要查找的约束条件如下：

或者只需使用单个约束条件：INumber&lt;TSelf&gt;

英文:

Introduced in .NET 7/C#11 is the new generic math. The constraints you are looking for are:

Or just use a single constraint: INumber&lt;TSelf&gt;
