Public Sub New ( _
    c As Char, _
    count As Integer _
)

[SecuritySafeCriticalAttribute]
public String(
    char c,
    int count
)

Parameters

Exceptions

Exception Condition
ArgumentOutOfRangeException

count is less than zero.

Remarks

Examples

The following simple code example demonstrates how you can create an instance of the String class with this constructor.

' Create a Unicode String with 5 Greek Alpha characters
Dim szGreekAlpha As New String(ChrW(&H319), 5)
' Create a Unicode String with a Greek Omega character
Dim szGreekOmega As New String(New Char() {ChrW(&H3A9), ChrW(&H3A9), _
                                           ChrW(&H3A9)}, 2, 1)

Dim szGreekLetters As String = String.Concat(szGreekOmega, szGreekAlpha, _
                                             szGreekOmega)

' Examine the result
outputBlock.Text &= szGreekLetters & vbCrLf

' The first index of Alpha
Dim iAlpha As Integer = szGreekLetters.IndexOf(ChrW(&H319))
' The last index of Omega
Dim iomega As Integer = szGreekLetters.LastIndexOf(ChrW(&H3A9))

outputBlock.Text &= String.Format("The Greek letter Alpha first appears at index {0}.", _
                  iAlpha) & vbCrLf
outputBlock.Text &= String.Format("The Greek letter Omega last appears at index {0}.", _
                  iomega) & vbCrLf

// Create a Unicode String with 5 Greek Alpha characters
String szGreekAlpha = new String('\u0319', 5);
// Create a Unicode String with a Greek Omega character
String szGreekOmega = new String(new char[] { '\u03A9', '\u03A9', '\u03A9' }, 2, 1);

String szGreekLetters = String.Concat(szGreekOmega, szGreekAlpha, szGreekOmega);

// Examine the result
outputBlock.Text += szGreekLetters + "\n";

// The first index of Alpha
int ialpha = szGreekLetters.IndexOf('\u0319');
// The last index of Omega
int iomega = szGreekLetters.LastIndexOf('\u03A9');

outputBlock.Text += "The Greek letter Alpha first appears at index " + ialpha +
    " and Omega last appears at index " + iomega + " in this String." + "\n";
