Syntax

声明
Public Overridable Function CompareItems ( _
    bstrSoFar As String, _

用法
Dim instance As CompletionSet

Dim bstrOther As String
Dim lCharactersToCompare As Integer
Dim plResult As Integer
Dim returnValue As Integer

returnValue = instance.CompareItems(bstrSoFar, _
    bstrOther, lCharactersToCompare, _
    plResult)

public virtual int CompareItems(
    string bstrSoFar,
    string bstrOther,
    int lCharactersToCompare,
    out int plResult
)

public:
virtual int CompareItems(
    String^ bstrSoFar, 
    String^ bstrOther, 
    int lCharactersToCompare, 
    [OutAttribute] int% plResult
)

abstract CompareItems : 
        bstrSoFar:string * 
        bstrOther:string * 
        lCharactersToCompare:int * 
        plResult:int byref -> int 
override CompareItems :

public function CompareItems(
    bstrSoFar : String, 
    bstrOther : String, 
    lCharactersToCompare : int, 
    plResult : int
) : int

Parameters

bstrSoFar
Type: System.String
The first string to compare.

bstrOther
Type: System.String
The second string to compare.

lCharactersToCompare
Type: System.Int32
The number of characters to compare.

plResult
Type: System.Int32%
[out] The result of the comparison.

Return Value

Type: System.Int32
If the method is successful, returns S_OK; otherwise, returns an error code (in which case the default comparison is used).

Implements

IVsCompletionSetEx.CompareItems(String, String, Int32, Int32%)

Remarks

The plResult should be returned as follows: if bstrSoFar comes before bstrOther, plResult < 0. If bstrSoFar is equivalent to bstrOther, plResult is 0. If bstrSoFar comes after bstrOther, plResult > 0.

This method is the implementation of the CompareItems method of the IVsCompletionSetEx interface.

By default this method is not implemented and returns plResult as 0 and E_NOTIMPL().
