public:
static ExpressionNode^ ConvertFromFilterNode(
    FilterNode^ filterNode
)

static member ConvertFromFilterNode : 
        filterNode:FilterNode -> ExpressionNode 

public static function ConvertFromFilterNode(
    filterNode : FilterNode
) : ExpressionNode

参数

返回值

示例

C#

string xpath = "Server/Database[like(@Name, 'msdb') or like(@Name,'m[as]%')]";
Urn urn = new SFC.Urn (xpath);

ExpressionNode node = ExpressionNode.ConvertFromFilterNode(fnode);

Note Urn and FilterNode are SFC classes.
