将嵌套连接sql查询转换为嵌套连接LINQ

Question

我正在尝试将嵌套连接sql查询转换为linq。我需要一些帮助才能将查询转换为linq。我正在使用vb.net。 这是我的SQL查询：

SELECT tblJobSkillMatrix_JS.fldJobTitleID,
       tblRSCFMainLevel.fldRSCFMainLevel, 
       tblRSCFSkill.fldRCSFSkill, 
       tblSkillLevelDefinition.fldSkillLevelNum, 
       tblJobSkillMatrix_JS.fldPriorityJobSkill
FROM ((tblJobSkillMatrix_JS 
INNER JOIN (tblRSCFMainLevel 
      INNER JOIN tblRSCFSkill 
              ON tblRSCFMainLevel.fldRSCFMainLevelID = tblRSCFSkill.fldRSCFMainLevelID) 
      ON tblJobSkillMatrix_JS.fldRSCFSkillID = tblRSCFSkill.fldRSCFSkillID) 
INNER JOIN tblSkillLevelDefinition ON 
           tblJobSkillMatrix_JS.fldSkillLevelID = tblSkillLevelDefinition.fldSkillLevelID) 
INNER JOIN tblRSCFSkillGroupLevel ON
           (tblRSCFSkillGroupLevel.fldRSCFSkillGroupLevelID = tblRSCFSkill.fldRSCFSkillGroupLevelID) 
      AND  (tblRSCFMainLevel.fldRSCFMainLevelID = tblRSCFSkillGroupLevel.fldRSCFMainLevelID)
WHERE (tblJobSkillMatrix_JS.fldJobTitleID='F74F5BCA-F33A-4AE1-9825-16B05AB274F4') 
  AND (tblRSCFMainLevel.fldRSCFMainLevel='People skills')
ORDER BY tblJobSkillMatrix_JS.fldPriorityJobSkill;
