Chilkat C# StringArray Class Reference

StringArray

* This is a freeware class/component/library.

Component for managing and manipulating collections of strings.

Object Creation

(C#)
Chilkat.StringArray obj = new Chilkat.StringArray();
(VB.NET)
Dim obj As New Chilkat.StringArray()

Properties

public int Count {get; }

The number of strings in the array.

public bool Crlf {get; set; }

If true, strings are always automatically converted to use CRLF line endings. If false, strings are automatically converted to use bare LF line endings.

public int Length {get; }

The number of strings in the array. (Identical to the Count property.)

public bool Trim {get; set; }

If true, whitespace, including carriage-returns and linefeeds, are automatically removed from the beginning and end of a string when added to the array.

public bool Unique {get; set; }

If true, the array does not allow duplicates. When an attempt is made to insert a string that already exists in the array, the insertion simply doesn't happen and no error is returned.

Methods

public void Append(string str);

Appends a string to the end of the array.

public bool AppendSerialized(string encodedStr);

Appends multiple strings to the end of the array. The encodedStrings argument is what is returned from the Serialize method (see below).

public bool Clear();

Remove all strings from the array.

public bool Contains(string str);

Returns true if the string is present in the array. The string comparisons are case sensitive.

public int Find(string str, int firstIndex);

Finds the index of the first string equal to the string passed. The search begins at beginIndex. If the string is not found, -1 is returned. The first string in the array is at index 0.

public int FindFirstMatch(string str, int firstIndex);

To be documented soon...

public string GetString(int index);

Returns the string at a location in the array. The first string is at index 0.

Returns a null on failure

public int GetStringLen(int index);

Returns Nth's string length, in characters. The first string is at index 0.

public void InsertAt(int index, string str);

Insert a string into the array at a particular index. Using index 0 will insert at the beginning.

public string LastString();

Returns the last string in the array.

Returns a null on failure

public bool LoadFromFile(string filename);

Adds strings from a file (one per line) into the string array.

Returns true for success, false for failure.

public void LoadFromText(string str);

Adds strings from an in-memory string (one per line) into the string array.

public string Pop();

Returns the last string and removes it from the array.

Returns a null on failure

public void Prepend(string str);

Adds a string to the beginning of the array.

public void Remove(string str);

Removes all strings equal to the string argument from the array.

public bool RemoveAt(int index);

Removes the string at a particular index.

public bool SaveNthToFile(int index, string filename);

Saves the Nth string in the StringArray object to a file.

Returns true for success, false for failure.

public bool SaveToFile(string filename);

Saves the array of strings to a file, one string per line.

Returns true for success, false for failure.

public string SaveToText();

Saves the array of strings to a single string, one string per line (separated by CRLF line endings).

public string Serialize();

Returns an string which is an encoded representation of all the strings in the array. The StringArray can be re-created by calling the AppendSerialized method. One reason this method exists is to make it easy to pass entire string arrays as a form parameter in a Web page.

Returns a null on failure

public void Sort(bool ascending);

Sorts the string array in ascending or descending order.

public void SplitAndAppend(string str, string boundary);

Splits a string at a character or substring boundary and adds each resulting string to the StringArray object.

public void Subtract(StringArray sa);

Subtracts the strings in the argument object from the calling object's set.

public void Union(StringArray array);

Performs the union set-operator. The caller will contain the union of two string arrays.
