參數

• geometryCollectionTaggedText
  型別：System.Data.SqlTypes.SqlChars
  Is the WKT representation of the geography instance you wish to return. geometrycollection_tagged_text is an nvarchar(max) expression.

• srid
  型別：System.Int32
  Is an int expression representing the spatial reference ID (SRID) of the geography instance you wish to return.

傳回值

型別：Microsoft.SqlServer.Types.SqlGeography
A geography instance.

備註

The OGC type of the geography instance returned by STGeomCollFromText is set to the corresponding WKT input.

This method throws an ArgumentException if the input is not valid.
