How to convert array to dictionary

Question

How to convert below fieldList array to dictionary as 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

You can use a linq lambda for this.

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

By adding StringComparer.OrdinalIgnoreCase you can ensure that the column name lookup is case insensitive.

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

Answer 2

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