StringBuilder::Insert Method (Int32, array<Char>)

Inserts the string representation of a specified array of Unicode characters into this instance at the specified character position.

Namespace:  System.Text
Assembly:  mscorlib (in mscorlib.dll)
public:
StringBuilder^ Insert(
	int index, 
	array<wchar_t>^ value
)

Parameters

index
Type: System::Int32

The position in this instance where insertion begins.

value
Type: array<System::Char>

The character array to insert.

Return Value

Type: System.Text::StringBuilder
A reference to this instance after the insert operation has completed.
ExceptionCondition
ArgumentOutOfRangeException

index is less than zero or greater than the length of this instance.

-or-

Enlarging the value of this instance would exceed MaxCapacity.

Existing characters are shifted to make room for the new text. The capacity of this instance is adjusted as needed.

If value is nullptr, the StringBuilder is not changed.

The following example demonstrates the Insert method.

using namespace System;
using namespace System::Text;
ref class Sample
{
private:

   //                           index: 012345 
   static String^ initialValue = "--[]--";
   static StringBuilder^ sb;

public:
   static void Main()
   {
      String^ xyz = "xyz";
      array<Char>^abc = {'a','b','c'};
      Char star = '*';
      Object^ obj = 0;
      bool xBool = true;
      Byte xByte = 1;
      short xInt16 = 2;
      int xInt32 = 3;
      long xInt64 = 4;
      Decimal xDecimal = 5;
      float xSingle = 6.6F;
      double xDouble = 7.7;

      // The following types are not CLS-compliant.
      UInt16 xUInt16 = 8;
      UInt32 xUInt32 = 9;
      UInt64 xUInt64 = 10;
      SByte xSByte = -11;

      //
      Console::WriteLine( "StringBuilder.Insert method" );
      sb = gcnew StringBuilder( initialValue );
      sb->Insert( 3, xyz, 2 );
      Show( 1, sb );
      sb->Insert( 3, xyz );
      Show( 2, sb );
      sb->Insert( 3, star );
      Show( 3, sb );
      sb->Insert( 3, abc );
      Show( 4, sb );
      sb->Insert( 3, abc, 1, 2 );
      Show( 5, sb );
      sb->Insert( 3, xBool ); // True
      Show( 6, sb );
      sb->Insert( 3, obj ); // 0
      Show( 7, sb );
      sb->Insert( 3, xByte ); // 1
      Show( 8, sb );
      sb->Insert( 3, xInt16 ); // 2
      Show( 9, sb );
      sb->Insert( 3, xInt32 ); // 3
      Show( 10, sb );
      sb->Insert( 3, xInt64 ); // 4
      Show( 11, sb );
      sb->Insert( 3, xDecimal ); // 5
      Show( 12, sb );
      sb->Insert( 3, xSingle ); // 6.6
      Show( 13, sb );
      sb->Insert( 3, xDouble ); // 7.7
      Show( 14, sb );

      // The following Insert methods are not CLS-compliant.
      sb->Insert( 3, xUInt16 ); // 8
      Show( 15, sb );
      sb->Insert( 3, xUInt32 ); // 9
      Show( 16, sb );
      sb->Insert( 3, xUInt64 ); // 10
      Show( 17, sb );
      sb->Insert( 3, xSByte ); // -11
      Show( 18, sb );

      //
   }

   static void Show( int overloadNumber, StringBuilder^ sbs )
   {
      Console::WriteLine( "{0,2:G} = {1}", overloadNumber, sbs );
      sb = gcnew StringBuilder( initialValue );
   }

};

int main()
{
   Sample::Main();
}
