Gets a value indicating whether the specified name is valid.
public:
bool IsValidName(System::String ^ name);public bool IsValidName (string name);abstract member IsValidName : string -> boolPublic Function IsValidName (name As String) As BooleanParameters
- name
- String
The name to validate.
Returns
true if the name is valid; otherwise, false.
Examples
The following code example provides an example INameCreationService.IsValidName method implementation. The method uses a string validation scheme that examines each character of the specified string to determine whether the specified string is a valid name. The method returns true if the string is valid, or false otherwise.
// Returns whether the specified name contains
// all valid character types.
virtual bool IsValidName( String^ name )
{
for ( int i = 0; i < name->Length; i++ )
{
Char ch = name[ i ];
UnicodeCategory uc = Char::GetUnicodeCategory( ch );
switch ( uc )
{
case UnicodeCategory::UppercaseLetter:
case UnicodeCategory::LowercaseLetter:
case UnicodeCategory::TitlecaseLetter:
case UnicodeCategory::DecimalDigitNumber:
break;
default:
return false;
}
}
return true;
}
// Returns whether the specified name contains
// all valid character types.
public bool IsValidName(string name)
{
for(int i = 0; i < name.Length; i++)
{
char ch = name[i];
UnicodeCategory uc = Char.GetUnicodeCategory(ch);
switch (uc)
{
case UnicodeCategory.UppercaseLetter:
case UnicodeCategory.LowercaseLetter:
case UnicodeCategory.TitlecaseLetter:
case UnicodeCategory.DecimalDigitNumber:
break;
default:
return false;
}
}
return true;
}
' Returns whether the specified name contains
' all valid character types.
Public Function IsValidName(ByVal name As String) As Boolean Implements INameCreationService.IsValidName
Dim i As Integer
For i = 0 To name.Length - 1
Dim ch As Char = name.Chars(i)
Dim uc As UnicodeCategory = [Char].GetUnicodeCategory(ch)
Select Case uc
Case UnicodeCategory.UppercaseLetter, UnicodeCategory.LowercaseLetter, UnicodeCategory.TitlecaseLetter, UnicodeCategory.DecimalDigitNumber
Case Else
Return False
End Select
Next i
Return True
End Function
Remarks
An implementation of the INameCreationService can have rules that define the parameters for valid names. This method can be implemented to validate a name and enforce those rules.
