我使用该库来解决线方程,它适用于从这个库中创建一个类对象,但是当我想重新创建该对象时,它会抛弃我:
System.InvalidOperationException:上下文中已存在活动模型。 在
Microsoft.SolverFoundation.Services.SolverContext.CreateModel ()
问题是,在计算第一个例子之后,我想要更改数据并单击按钮并获得另一个例子的结果。
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;
}
}}
答案 0 :(得分:3)
首先致电ClearModel
:
SolverContext context = SolverContext.GetContext();
context.ClearModel();
Model model = context.CreateModel();
