richtextbox1 があり、すべての「USER1」を削除したいと考えています。以下から、文が ALTER TABLE で始まり、"USER1" で構成されている場合。C#を使用してそれを行う最良の方法は何ですか

リッチテキストボックスの私のテキスト

DROP INDEX XIE2TBL_A;

DROP INDEX XPKTBL_A;

ALTER TABLE "COURSE" DROP CONSTRAINT "CRSE_CRSE_FK";

ALTER TABLE "ENROLLMENT" DROP CONSTRAINT "ENR_STU_FK";

ALTER TABLE "ENROLLMENT" DROP CONSTRAINT "ENR_SECT_FK";

ALTER TABLE "ENROLLMENT" ADD CONSTRAINT "ENR_STU_FK" FOREIGN KEY ("STUDENT_ID") REFERENCES "USER1"."STUDENT"("STUDENT_ID") ENABLE;

ALTER TABLE "ENROLLMENT" ADD CONSTRAINT "ENR_SECT_FK" FOREIGN KEY ("SECTION_ID") REFERENCES "USER1"."SECTION"("SECTION_ID") ENABLE;

ALTER TABLE "GRADE" DROP CONSTRAINT "GR_ENR_FK";

ALTER TABLE "GRADE" DROP CONSTRAINT "GR_GRTW_FK";

ALTER TABLE "GRADE" ADD CONSTRAINT "GR_ENR_FK" FOREIGN KEY ("STUDENT_ID","SECTION_ID") REFERENCES "USER1"."ENROLLMENT"("STUDENT_ID","SECTION_ID") ENABLE;

ALTER TABLE "GRADE" ADD CONSTRAINT "GR_GRTW_FK" FOREIGN KEY ("SECTION_ID","GRADE_TYPE_CODE") REFERENCES "USER1"."GRADE_TYPE_WEIGHT"("SECTION_ID","GRADE_TYPE_CODE") ENABLE;

ALTER TABLE "GRADE_TYPE_WEIGHT" DROP CONSTRAINT "GRTW_GRTYP_FK";

ALTER TABLE "GRADE_TYPE_WEIGHT" DROP CONSTRAINT "GRTW_SECT_FK";

ALTER TABLE "GRADE_TYPE_WEIGHT" ADD CONSTRAINT "GRTW_GRTYP_FK" FOREIGN KEY ("GRADE_TYPE_CODE") REFERENCES "USER1"."GRADE_TYPE"("GRADE_TYPE_CODE") ENABLE;

ALTER TABLE "GRADE_TYPE_WEIGHT" ADD CONSTRAINT "GRTW_SECT_FK" FOREIGN KEY ("SECTION_ID") REFERENCES "USER1"."SECTION"("SECTION_ID") ENABLE;

ALTER TABLE "INSTRUCTOR" DROP CONSTRAINT "INST_ZIP_FK";

ALTER TABLE "INSTRUCTOR" ADD CONSTRAINT "INST_ZIP_FK" FOREIGN KEY ("ZIP") REFERENCES "USER1"."ZIPCODE"("ZIP") ENABLE;

ALTER TABLE "SECTION" DROP CONSTRAINT "SECT_INST_FK";

あなたのrichTextBox1.Text場合、各行が次で始まるかどうかを確認する必要はありませんALTER TABLE。 

 richTextBox1.Text = richTextBox1.Text.Replace("REFERENCES \"USER1\".", "REFERENCES ");

を確認したい場合は、以下ALTER TABLEを少し使用しますRegEx。

Regex reg = new Regex("(ALTER TABLE .+ REFERENCES\\s+)\"USER1\"[.](.+)");
richTextBox1.Text = reg.Replace(richTextBox1.Text, "$1$2");
