C# 如何将文件内容映射到现有字典c

因此，我试图做的是基于一个唯一的项映射两个不同文件的内容，在本例中是sampleName。其中一个文件的内容先前已添加到字典中，其中包含一个具有属性的列表和一个sampleName作为键

此示例名称也出现在具有以下格式的第二个文件中：

*Projectnummer;Datum;wetenschappelijke_naam;zakje;ring;klantnr         
"aNumber";"aDate";"scientificName";"123456";"12";"aNumber" etc..* 

如果123456是sampleName，则在以前生成的字典中也会出现这种情况

这里的问题是，对于当前代码，字典CorrectSamplesDict中的错误sampleCode中添加了错误的项。信息的添加不是基于匹配的样本号，而是基于文件中行的顺序

如何检查样本名称是否匹配，以及需要添加哪些信息

在您的代码中有许多事情看起来很奇怪：

if (correctSamplesDict.TryGetValue(sample.SampleName, out sampleProperties))
{
    foreach (KeyValuePair<string, List<Sample>> items in correctSamplesDict)
    {
        foreach (Sample sampleValue in items.Value)
        {
            //skip...
        }
    }
    correctSamplesDict[sampleVal.SampleName] = sampleProperties;
}

您正在布尔变量上使用开关/大小写，而不是if/else

您正在使用一个字典您可以共享您读取@user3309936的示例文件吗？您给出的示例不清楚您在代码中实现的逻辑。第一个示例文件的内容在另一部分代码中实现并保存在字典中。我在本部分中阅读的示例具有我在问题中解释的格式。标题如下所示：Projectnummer；资料wetenschappelijke_naam；扎克耶桑普伦姆；戒指三K党。这个标题包含了所有的信息。我不太清楚我是否理解你想知道的内容。。

if (correctSamplesDict.TryGetValue(sample.SampleName, out sampleProperties))
{
    foreach (KeyValuePair<string, List<Sample>> items in correctSamplesDict)
    {
        foreach (Sample sampleValue in items.Value)
        {
            //skip...
        }
    }
    correctSamplesDict[sampleVal.SampleName] = sampleProperties;
}

if (correctSamplesDict.TryGetValue(sample.SampleName, out sampleProperties))
{
    foreach (Sample sampleValue in sampleProperties)
    {
        sampleValue.ProjectDate = sample.ProjectDate;
        sampleValue.ProjectNumber = sample.ProjectNumber;
        sampleValue.CustomerNumber = sample.CustomerNumber;
        sampleValue.RingNumber = sample.RingNumber;
        sampleValue.ScientificName = sample.ScientificName;
    }
}
