      <para>Represents an immutable series of characters.</para>
    </summary>
    <remarks>
      <para>An <paramref name="index" /> is the position of a character within a
   string. The first character in the string is at index 0. The length of a string
   is the number of characters it is made up of. The last accessible <paramref name="index" />
   of a string
   instance is <see cref="P:System.String.Length" />
   - 1.</para>
      <para>Strings are immutable; once created, the contents of a
<see cref="T:System.String" /> do not change. Combining 
   operations, such as <see cref="M:System.String.Replace(System.Char,System.Char)" />, cannot alter existing strings.
   Instead, such operations return a new string that contains the results of the
   operation, an unchanged string, or the null value. To perform modifications to a
<see cref="T:System.String" /> use the 
<see cref="T:System.Text.StringBuilder" /> 
.</para>
      <para>Implementations of <see cref="T:System.String" /> are required to contain
a variable-length character buffer positioned a fixed number of bytes after
the beginning of the String object. <block subset="none" type="note"> The <see cref="P:System.Runtime.CompilerServices.RuntimeHelpers.OffsetToStringData" />
method returns
the number of bytes between the start of the String object and the character buffer. This
information is intended primarily for use by compilers, not application programmers. For additional information, see <see cref="P:System.Runtime.CompilerServices.RuntimeHelpers.OffsetToStringData" />
.</block></para>
      <block subset="none" type="note">
        <para>Comparisons and searches are case-sensitive by default
      and unless otherwise specified, use the culture defined for the current thread
      to determine the order of the alphabet used by the strings. This information is
      then used to compare the two strings on a character-by-character basis. Upper
      case letters evaluate greater than their lower case equivalents.</para>
        <para>The following characters are considered white space when present in a
      System.String instance: 0x9, 0xA, 0xB, 0xC, 0xD, 0x20, 0xA0, 0x2000, 0x2001,
      0x2002, 0x2003, 0x2004, 0x2005, 0x2006, 0x2007, 0x2008, 0x2009, 0x200A, 0x200B,
      0x3000, and 0xFEFF.</para>
        <para>The null character is defined as hexadecimal 0x00.</para>
        <para>The <see cref="T:System.String" />(<see cref="T:System.String" />) constructor is
   omitted for performance reasons. If you need a copy of a <see cref="T:System.String" />, consider using
<see cref="M:System.String.Copy(System.String)" /> or 
   the <see cref="T:System.Text.StringBuilder" />
   class.</para>
        <para>To insert a formatted string representation of an object
   into a string use the <see cref="M:System.String.Format(System.String,System.Object)" /> methods.
   These methods take one or more arguments to be formatted and a format string.
   The format string contains literals and zero or more format
   specifications in the form { <paramref name="N" /> [, <paramref name="M" /> ][: <paramref name="formatSpecifier" />
   ]}, where:
   </para>
        <list type="bullet">
          <item>
            <term>
              <paramref name="N" /> is a zero-based integer 
      indicating the argument to be formatted. If the actual argument is a null
      reference, then an empty string is used in its place.</term>
          </item>
          <item>
            <term>
              <paramref name="M" /> is an optional integer
      indicating the minimum width of the region to contain the formatted value of
      argument <paramref name="N" />
      . If the length of
      the string representation of the value is less than <paramref name="M" />, then the
      region is padded with spaces. If <paramref name="M" /> is negative, the formatted value
      is left justified in the region; if <paramref name="M" /> is positive, then the value is right
      justified. If <paramref name="M" /> is
      not specified, it is assumed to be zero indicating that neither padding nor
      alignment is customized. Note that if the length of the formatted value is
      greater than <paramref name="M" />, then <paramref name="M" /> is ignored.</term>
          </item>
          <item>
            <term>
              <paramref name="formatSpecifier" /> is an
      optional string that determines the representation used for arguments.
      For example, an integer can be represented in hexadecimal or decimal format, or as a
      monetary value. If <paramref name="formatSpecifier" /> is
      omitted and an argument implements the <see cref="T:System.IFormattable" /> interface, then a null reference is
      used as the <see cref="M:System.IFormattable.ToString(System.String,System.IFormatProvider)" /> format specifier. Therefore, all implementations of
   <see cref="M:System.IFormattable.ToString(System.String,System.IFormatProvider)" /> are required to allow a null reference as
      a format specifier, and return a string containing the default representation
      of the object as determined by the object type. For additional information on
      format specifiers, see <see cref="T:System.IFormattable" />
      .</term>
          </item>
        </list>
        <para>If an object referenced in the format string implements
<see cref="T:System.IFormattable" />, 
   then the <see cref="M:System.IFormattable.ToString(System.String,System.IFormatProvider)" /> method of the object provides the formatting. If the
   argument does not implement <see cref="T:System.IFormattable" />, then the <see cref="M:System.Object.ToString" /> method of the object provides default
   formatting, and <paramref name="formatSpecifier" />
   , if present, is ignored.
   For an example that demonstrates this, see Example 2.</para>
        <para>To include a
   curly bracket in a formatted
   string, specify the bracket twice; for example, specify "{{" to
   include "{" in the formatted string. See Example 1.</para>
        <para>The <see cref="T:System.Console" /> class exposes the same functionality as the <see cref="M:System.String.Format(System.String,System.Object)" /> methods
via <see cref="M:System.Console.Write(System.String,System.Object)" /> and <see cref="M:System.Console.WriteLine" />. The primary difference is that the
<see cref="M:System.String.Format(System.String,System.Object)" /> 
methods return the formatted string, while the
System.Console methods write the formatted string to a stream.</para>
