如何将数组转换为字典

Question

如何将下面的 fieldList 数组转换为字典 Dictionary<string,column> (i.e. Dictionary of name property of column class as key and value property of dictionary as column object)。

public class columninfo
{
 public string name {get;set;}
 public column[] fieldList {get;set;}
}

public class column
{
  public string name {get;set;}
  public string fieldname {get;set}
  public string format {get;set;}
}

Answer 1

fieldList.ToDictionary(c=>c.name, c=>c);

Answer 2

您可以为此使用 linq lambda。

column[] columns = getColumninfo();
columns.ToDictionary(x => x.name, y => y);

通过添加 StringComparer.OrdinalIgnoreCase 可以确保列名查找不区分大小写。

columns.ToDictionary(x => x.name, y => y, StringComparer.OrdinalIgnoreCase);
