C# 类与结构之间的交互

c# .net struct

C# 类与结构之间的交互,c#,.net,struct,class-design,C#,.net,Struct,Class Design,好的，我项目中的一个类使用了这个方法 public static MemberName SplitTdsName(string tdsName) { NameSplitter preSplitName = new NameSplitter(tdsName); return preSplitName; } MemberName是一个结构： public struct MemberName { public string Title;

好的，我项目中的一个类使用了这个方法

public static MemberName SplitTdsName(string tdsName)
    {
        NameSplitter preSplitName = new NameSplitter(tdsName);
        return preSplitName;
    }

MemberName是一个结构：

public struct MemberName
{
    public string Title;
    public string FirstNames;
    public string LastNames;

    public MemberName(string title, string firstNames, string lastNames)            
    {            
        Title = title;
        FirstNames = firstNames;
        LastNames = lastNames;
    }
}

和Namespliter类：

public NameSplitter(string fullName)
    {
        nameInFull = fullName;
        SetAllowedTitles();
        SplitNamesAndRemovePeriods();
        SetTitles();
        MemberName splitName = new MemberName(titles, firstNames, lastNames);
        return splitName;
    }

这不起作用，因为当我将public NameSplitter更改为public MemberName NameSplitter时，splitdsname方法告诉我NameSplitter没有一个只接受一个参数的方法

我不知道如何解决这个问题，也不知道如何让它发挥作用。我是否需要将NameSplitter更改为NameSplitter静态类

注意：我知道代码是错误的

与：

public static MemberName SplitTdsName(string tdsName)
    {
        return NameSplitter.NameSplitter(tdsName);
    }

public static MemberName NameSplitter(string fullName)
    {
        nameInFull = fullName;
        SetAllowedTitles();
        SplitNamesAndRemovePeriods();
        SetTitles();
        MemberName splitName = new MemberName(titles, firstNames, lastNames);
        return splitName;
    }

    public MemberName(string title, string firstNames, string lastNames)            
    {            
        Title = title;
        FirstNames = firstNames;
        LastNames = lastNames;
    }

您的代码中有几个问题，很明显它无法编译

1）构造函数中不能有

返回值
public NameSplitter(string fullName)
{
     ...
     return splitName;
}

2） 返回类型和返回语句必须一致。这里返回一个NameSplitter
，但函数承诺了一个MemberName
：
public static MemberName SplitTdsName(string tdsName)
{
   NameSplitter preSplitName = new NameSplitter(tdsName);
   return preSplitName;
}


快速修复（可能不完整，未经测试）
然后这个方法就变成了
public static MemberName SplitTdsName(string tdsName)
{
    NameSplitter preSplitName = new NameSplitter(tdsName);
    return preSplitName.MemberName ;
}

但我不认为MemberName应该是一个结构，类也是一个不错的选择

 您应该使该方法成为一个静态方法，返回MemberName并将结果分配给MemberName变量，而不是NameSplitter（在SplitTdsName方法中）
您应该使该方法成为一个静态方法，返回MemberName并将结果分配给MemberName变量，而不是NameSplitter（在SplitdDSName方法中）
尝试实现如下类：
    public static class NameSplitter
    {
        public static MemberName Split(string fullName)
        {
            ...
            MemberName splitName = new MemberName(titles, firstNames, lastNames);
            return splitName;
        }
    }

然后使用asMemberName mn=NameSplitter.Split（“”）
最终代码可以如下所示：
    public static class YourClass
    {
        ...
        public static MemberName SplitTdsName(string tdsName)
        {
            MemberName preSplitName = NameSplitter.Split(tdsName);
            return preSplitName;
        }
    }

    public static class NameSplitter
    {
        ...
        public static MemberName Split(string fullName)
        {
            nameInFull = fullName;
            SetAllowedTitles();
            SplitNamesAndRemovePeriods();
            SetTitles();
            MemberName splitName = new MemberName(titles, firstNames, lastNames);
            return splitName;
        }
    }

    public struct MemberName
    {
        public string Title;
        public string FirstNames;
        public string LastNames;

        public MemberName(string title, string firstNames, string lastNames)
        {
            Title = title;
            FirstNames = firstNames;
            LastNames = lastNames;
        }
    }

尝试实现类，如：
    public static class NameSplitter
    {
        public static MemberName Split(string fullName)
        {
            ...
            MemberName splitName = new MemberName(titles, firstNames, lastNames);
            return splitName;
        }
    }

最终代码可以如下所示：
    public static class YourClass
    {
        ...
        public static MemberName SplitTdsName(string tdsName)
        {
            MemberName preSplitName = NameSplitter.Split(tdsName);
            return preSplitName;
        }
    }

    public static class NameSplitter
    {
        ...
        public static MemberName Split(string fullName)
        {
            nameInFull = fullName;
            SetAllowedTitles();
            SplitNamesAndRemovePeriods();
            SetTitles();
            MemberName splitName = new MemberName(titles, firstNames, lastNames);
            return splitName;
        }
    }

    public struct MemberName
    {
        public string Title;
        public string FirstNames;
        public string LastNames;

            Title = title;
            FirstNames = firstNames;
            LastNames = lastNames;
        }

这段代码曾经编译过吗？您似乎试图从我假设的名称过滤器构造函数中返回一些东西-您不能这样做。请提供完整的NameSplitter
代码。您的NameSplitter构造函数只能返回NameSplitter类，不能返回MemberName类。也许您需要一个简单的构造函数，然后是一个“拆分”字符串并返回MemberName的方法object@sll代码从不编译不，我意识到这种交互是错误的，我只是不知道如何使它正确。这不是交互问题，更多的是编码错误。这段代码是否编译过？您似乎试图返回我假设是名称过滤器构造函数中的某个内容-您不能这样做。请提供完整的NameSplitter
