String Constructor (Char*, Int32, Int32)
Initializes a new instance of the String class to the value indicated by a specified pointer to an array of Unicode characters, a starting character position within that array, and a length.
Assembly: mscorlib (in mscorlib.dll)
[CLSCompliantAttribute(false)] public String( char* value, int startIndex, int length )
startIndex or length is less than zero, value + startIndex cause a pointer overflow, or the current process does not have read access to all the addressed characters.
value is null.
value specifies an array that contains an invalid Unicode character, or value + startIndex specifies an address less than 64000.
If length is zero, an Empty instance is initialized.
This constructor copies Unicode characters from value, starting at startIndex and ending at (startIndex + length - 1).
If the specified range is outside of the memory allocated for the sequence of characters, the behavior of this constructor is system dependent. For example, such a situation might cause an access violation.
In C#, this constructor is defined only in the context of unsafe code.
