如何处理 Microsoft Solver Foundation 中已经存在的活动模型？

Question

我用这个库来求解线方程，它适用于从这个库中创建一个 class 对象，但是当我想重新创建对象时，它把我扔掉了：

System.InvalidOperationException: There is already an active model in the context. At Microsoft.SolverFoundation.Services.SolverContext.CreateModel ()

问题是在计算完第一个例子后，我想更改数据并单击按钮并获取另一个例子的结果。

class LinearResolve
{
    public string[] Zmienne = new string[3];

    public LinearResolve(string[] table)
    {
        Zmienne = table;
    }

    public string Solver()
    {
        SolverContext context = SolverContext.GetContext();
        Model model = context.CreateModel();
        Decision a = new Decision(Domain.Real, "a");
        Decision b = new Decision(Domain.Real, "b");
        Decision c = new Decision(Domain.Real, "c");
        model.AddDecisions(a, b, c);
        model.AddConstraint("eqA", Zmienne[0]);
        model.AddConstraint("eqB", Zmienne[1]);
        model.AddConstraint("eqC", Zmienne[2]);
        Solution solution = context.Solve();
        string results = solution.GetReport().ToString();
        return results;
    }
}}

先呼叫ClearModel：

SolverContext context = SolverContext.GetContext();
context.ClearModel();
Model model = context.CreateModel();
