参数
- geometryCollectionTaggedText
类型:System.Data.SqlTypes. . :: . .SqlChars
The WKT representation of the SqlGeometry instance you wish to return.
- srid
类型:System. . :: . .Int32
An integer expression that represents the spatial reference ID (SRID) of the SqlGeometry instance you wish to return.
返回值
类型:Microsoft.SqlServer.Types. . :: . .SqlGeometry
A SqlGeometry value constructed from the specified WKT representation.
注释
The OGC type of the SqlGeometry instance returned by STGeomCollFromText is set to the corresponding WKT input.
This method will throw an exception if the input is not valid.
This member is static.
