Visual Studio 2010,C#,Ninject版本3.0.0.0。
有一个提供字符串变量X的循环。在类中有对Ninject的引用。在循环内部,变量在kernel.Get方法中用于选择要使用的类。
我的印象是Ninject能够确定正确的类而不必使用Ninject内核。获取方法。这只是另一种依赖,这是Ninject应该帮助避免的情况。
有没有办法配置Ninject来确定基于变量X使用的正确类而不使用kernel.Get?我想在没有在课堂上使用Ninject引用的情况下完成此任务。
我有搜索stackoverflow和网络一般来回答这个问题。我本可以错过一些东西或者误解了一些东西,但我已经花了很多时间搜索。
感谢。
好的,有几个类使用这种技术。这是一个:
代码:
foreach (string nodePattern in patternList.GetPattern())
{
numberOfPatterns++;
tempReturn = true;
nodeStack.LoadbatchStructs(nodeStructure);
patternStack.LoadPattern(nodePattern);
PatternProperty patternProp = patternStack.PopPattern();
while (!(patternProp.Identifier == "EndOfStack"))
{
matchMode = int.TryParse(patternProp.PatternType, out outIntTestResult)
? "#"
: patternProp.PatternType;
int.TryParse(patternProp.PatternType, out loopCount);
classNames.TryGetValue(matchMode, out className);
IComparePatternAndData patternMatcher = kernel.Get<IComparePatternAndData>(className);
tempReturn &= patternMatcher.MatchesPattern(nodeStack, patternProp.Identifier, loopCount);
if (tempReturn == false)
{
falseMatches++;
break;
}
else
{
patternProp = patternStack.PopPattern();
//If there are no more pattern units to match, but there are more node identifiers (e.g. form identifiers or template IDs),
//then the pattern didn't match. So set the tempReturn to false.
if (patternProp.Identifier == "EndOfStack" &&
!(nodeStack.PeekStructData() == "ENDNODE"))
{
tempReturn = false;
}
}
} //Next unit of pattern string
if (tempReturn == true) numberOfMatches++;
} // Next pattern string
if (numberOfMatches > 0)
{
tempReturn = true;
}
else
{
tempReturn = false;
}
return tempReturn;
Ninject绑定。
Bind<IComparePatternAndData>().To<DataMatchesPatternCount>().Named("DataMatchesPatternCount");
Bind<IComparePatternAndData>().To<DataMatchesPatternErotem>().Named("DataMatchesPatternErotem");
Bind<IComparePatternAndData>().To<DataMatchesPatternStar>().Named("DataMatchesPatternStar");
Bind<IComparePatternAndData>().To<DataMatchesPatternPlus>().Named("DataMatchesPatternPlus");
类构造函数:
public class ValidateNodeStructure : IValidateNodeStructure
{
private readonly INodeStructure nodeStruct;
private readonly BatchStructStack nodeStack;
private INodePattern patternList;
private readonly IPatternStack patternStack;
private readonly IGetClassNameFromPatternType getClassNames;
public ValidateNodeStructure(INodeStructure nodeStructure, BatchStructStack nodeStack, IPatternStack patternStack, IGetClassNameFromPatternType getClassNames)
{
this.nodeStruct = nodeStructure;
this.nodeStack = nodeStack;
this.patternStack = patternStack;
this.getClassNames = getClassNames;
}
答案 0 :(得分:0)
你正在使用像字典一样的ninject,但你的代码中已经有了一本字典:classNames
。
不是将Named
添加到IComparePatternAndData
的绑定中,为什么不将“name”数据添加到IComparePatternAndData
接口(作为属性)并注入所有IComparePatternAndData
1}}进入IGetClassNameFromPatternType
- (当然你应该更改名称然后b / c它提供不同的功能。我已将其重命名为IPatternDictionary
)。
public interface IComparePatternAndData
{
int PatternId { get; }
// of course the actual compare method(s) go here as well...
}
public interface IPatternDictionary
{
bool TryGetValue(int key, out IComparePatternAndData value);
}
public class PatternDictionary : Dictionary<int, IComparePatternAndData>, IPatternDictionary
{
public PatternDictionary(IComparePatternAndData[] patterns)
{
foreach (IComparePatternAndData pattern in patterns)
{
this[pattern.PatternId] = pattern;
}
}
}
绑定:
Bind<IPatternDictionary>().To<PatternDictionary>();
Bind<IComparePatternAndData>().To<DataMatchesPatternCount>();
Bind<IComparePatternAndData>().To<DataMatchesPatternErotem>();
Bind<IComparePatternAndData>().To<DataMatchesPatternStar>();
Bind<IComparePatternAndData>().To<DataMatchesPatternPlus>();
用法:
IComparePatternAndData patternMatcher;
patternDictionary.TryGetValue(matchMode, out patternMatcher);
而不是:
classNames.TryGetValue(matchMode, out className);
IComparePatternAndData patternMatcher = kernel.Get<IComparePatternAndData>(className);
