Question

我正在尝试使用get（）来设置文本值并访问它的简单操作。

场景：我正在研究Visual Studio中的框架。

    private string saveValueName = "";
    public string GetText()
    {
        return saveValueName;
    }

    public void SetText(string output)
    {

        DynamicValuesManager.Instance.SaveValue(saveValueName, output, true);

    }

我的问题： 1.我需要保存我在SetText中的值，并在调用GetText（）时在下一步中使用它。

您是否建议在此方案中使用getter / setter？

Answer 1

这可以通过C＃中的属性来完成。

df = structure(list(id = c(1L, 1L, 1L, 2L, 2L, 2L), result = c("a", 
        "b", "c", "e", "f", "g")), .Names = c("id", "result"),
        class = "data.frame", row.names = c(NA, -6L))

现在您可以通过调用它来使用该属性，如下所示：

public string saveValueName { get; set; }

Answer 2

private string saveValueName = string.empty; //better practice
public string GetText()
{
    return saveValueName;
}

public void SetText(string output)
{
   //save the incoming parameter to your private property:
   saveValueName = output //this really should be called input since you are passing it in as a parameter but no biggie

   //Not really sure what this function does?
    DynamicValuesManager.Instance.SaveValue(saveValueName, output, true);

}
//Sample code to retrieve the value passed in:
 tempVariable = yourClassName.GetText()

使用它：

private string saveValueName = "";
public string GetText()
{
    return this.saveValueName;
}

public void SetText(string output)
{

    this.saveValueName = output;

}

还有另一种处理方法。它在C＃中被称为属性。你可以这样做：

public string SaveValueName {get; set; }

通过这种方式，您可以轻松地为此设置值，而无需调用函数。例如，设置一个值你会这样做：

// obj is the object of the class
obj.SaveValueName = "some value here";

Answer 4

疯狂猜测（基于DynamicValuesManager.Instance.SaveValue调用）：您可能正在寻找类似Dictionary和indexer的内容：

  public class MyClass<T> {
    private Dictionary<string, T> m_Values = new Dictionary<string, T>();

    public T this[string name] {
      get {
        return m_Values[name];
      }
      set {
        if (m_Values.ContainsKey(name))
          m_Values[name] = value;
        else
          m_Values.Add(name, value);
      }
    }
  }

  ...

  var test = new MyClass<int>();

  test["abc"] = 1;
  test["x"] = 2;
  test["pqr"] = 55;

  Console.WriteLine(test["x"]);

甚至ExpandoObject：

  using System.Dynamic;

  ... 

  dynamic test = new ExpandoObject();

  test.abc = 1;
  test.x = 2;
  test.pqr = 55; 

  Console.WriteLine(test.x);

只是为了扩展Moher的答案。如果已经设置了变量，你就不应该写一个变量。

    private string saveValueName = "";
    public string GetText()
    {
        return this.saveValueName;
    }

    public void SetText(string output)
    {
        if (!string.Equals(output, saveValueName))
        {
            this.saveValueName = output;
        }
    }

如果您使用MVVM样式，则在设置变量时需要通知属性已更改。

保存设定值并在get in c＃中使用它
