Type: System.Collections.DictionaryEntry

System.Collections.DictionaryEntry Structure

Assembly: Mscorlib.dll
Namespace: System.Collections

Summary: Defines a dictionary key-and-value pair that can be set or retrieved.

C# Syntax:

[Serializable]
public struct DictionaryEntry

Thread Safety

Public static (non-instance) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.

Remarks

The IDictionaryEnumerator.Entry method returns an instance of this class.

The foreach statement of the C# language (for each) requires the type of each element in the collection. Since each element of a collection based on IDictionary is a key-and-value pair, the element type is not the type of the key or the type of the value. Instead, the element type is DictionaryEntry. For example: foreach (DictionaryEntry myEntry in myHashtable) {...}

Summary: Initializes an instance of the DictionaryEntry class with the specified key and value.

C# Syntax:


            public DictionaryEntry(
   object key,
   object value
);

Parameters:

key

The object defined in each key-and-value pair.

Property: Key (read-write)

Summary: Gets or sets the key in the key-and-value pair.

C# Syntax:


            public object Key {get; set;}

Return to top

Property: Value (read-write)

Summary: Gets or sets the value in the key-and-value pair.

C# Syntax:


            public object Value {get; set;}

Return to top

Method: Equals(
object obj
)

Inherited
See base class member description: System.ValueType.Equals

Summary: Indicates whether this instance and a specified object are equal.

C# Syntax:


            public override bool Equals(
   object obj
);

Parameters:

obj

Another object to compare to.

Return Value:: true if obj and this instance are the same type and represent the same value; otherwise, false.

Method: Finalize()

Inherited
See base class member description: System.Object.Finalize

C# Syntax:


            ~DictionaryEntry();

Method: GetHashCode()

Inherited
See base class member description: System.ValueType.GetHashCode

Summary: Returns the hash code for this instance.

C# Syntax:


            public override int GetHashCode();

Return Value:: A 32-bit signed integer that is the hash code for this instance.

Remarks

The ValueType.GetHashCode method applies to types derived from ValueType. One or more fields of the derived type is used to calculate the return value. If one or more of those fields contains a mutable value, the return value might be unpredictable, and unsuitable for use as a key in a hash table.

For more information, see Object.GetHashCode, and Hashtable.

Method: ToString()

Inherited
See base class member description: System.ValueType.ToString

Summary: Returns the fully qualified type name of this instance.

C# Syntax:


            public override string ToString();

Return Value:: A String containing a fully qualified type name.
